Quantitative Analysis by Spectrophotometric Methods Essay Example Quantitative Analysis by Spectrophotometric Methods Paper Quantitative Analysis by Spectrophotometric Methods Paper Abstract In this experiment, the absorbance of KMnO4 was measured by spectrophotometric method to determine the molar concentration and the molar extinction coefficient of KMnO4. In part 1, in order to determine the maximum absorbance wavelength of KMnO4, we measured the absorbance of the sample solution which contains KMnO4 at the wavelengths between 330nm and 660nm, and plotted the ? and A points; the ? max was 530nm. In part 2, the effect of concentration on the absorbance was examined. We prepared five differently concentrated (but, same path length) solutions, and measured the absorbance of them at the ? ax(530nm) discovered in part 1; According to the results, higher concentrated solution had higher absorbance value. The extinction coefficient(? ) could be calculated from the results determined in part 2 and Beer’s Law; ? = 1. 7 x 103. In part 3, the absorbance of the KMnO4 solution of unknown concentration was measured, and using Beer’s law and dilution equation, the initial concentration of the unknown was determined; The concentration of the solution (unknown # : 15) was calculated to be 3. 3 x 10-3M. Introduction Our eyes are sensitive to light which lies in a very small region of the electromagnetic spectrum labeled visible light. This visible light corresponds to a wavelength range of 400 700 nanometers (nm) and a color range of violet through red. The human eye is not capable of seeing radiation with wavelengths outside the visible spectrum. The visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red. Ultraviolet radiation has a shorter wavelength than the visible violet light. Infrared radiation has a longer wavelength than visible red light. The white light is a mixture of the colors of the visible spectrum. Black is a total absence of light. Figure 5. 1 The electromagnetic spectrum. Although visible light acts as a wave in some respects, it also displays properties characteristic of particles. The particle-like properties of visible light are exhibited through small, energy-bearing entities known as photons. The energy of a photon is: E photon = hc / ? (1) where h = Plancks constant, 6. 626 x 10-34 J/s, c = speed of light, 3. 00 x 108 m/s, and ? = wavelength of light. Light is energy, and when energy is absorbed by a chemical it results in a change in energy levels of the chemical. Molecules normally exist in discrete energy levels. Vibrational energy levels exist because molecular bonds vibrate at specific frequencies. Electronic energy levels exist because electrons in molecules can be excited to discrete, higher energy orbitals. The energy (E) of light depends on its wavelength. Longer wavelengths (infrared) have less energy than shorter wavelengths (ultraviolet). A molecule will absorb energy (light) when the energy (or wavelength) exactly matches the energy difference between the two energy states of the molecule. In absorption, light - sunlight which is white light - strikes an object and part of the light may be absorbed by the object. The light we see coming from that object is the light which was not absorbed by the object. We see the not-absorbed light as the color of the object. If no light is absorbed, the object appears to be colorless. A spectrophotometer is employed to measure the amount of light that a sample absorbs. The instrument operates by passing a beam of light through a sample and measuring the intensity of light reaching a detector. The beam of light consists of a stream of photons. When a photon encounters a molecule, there is a chance the molecule will absorb the photon. This absorption reduces the number of photons in the beam of light, thereby reducing the intensity of the light beam. The ratio of transmitted light intensity(I) to the incident light intensity(I0) is the transmittance, T: T = I / I0 (2) The amount of light a sample absorbs is affected by its concentration. If there are samples of same substances but different concentrations, the amount of the absorbed light will be different. In higher concentrated solution, more absorbing molecules are present in the path of the light, and the chance the light strikes the molecules will increase. So, more light will be absorbed by the sample; less light will be transmitted. In contrast, in lower concentrated solution, less light will be absorbed, and more light will be transmitted. The concentration is represented by the symbol C and is typically measured in mole/L. Another factor that affects the amount of light a sample absorbs is the path length which is the length of sample that the light passes through. The path length is represented by the symbol l and is typically measured in centimeters. When the light travels through longer distance, it will strike more absorbing molecules, so more light will be absorbed, and less light will be transmitted. The relationship of two factors (path length concentration) can be combined to yield a general equation called Beers Law. log10T = A = ? lC (3) The quantity ? is the molar absorptivity; in older literature it is sometimes called the molar extinction coefficient. It is the measure of how strongly a substance absorbs light at a particular wavelength; a larger extinction coefficient means that substance absorbs more light. The units of ? are usually in M-1cm-1 or L mol-1cm-1. A is the absorbance of light by a sample, and in this experiment, it was measured directly by a spectrophotometer. Experimental 1. Maximum Absorbance Wavelength: For the first part of this experiment, we determined the wavelength at which a selected substance (KMnO4) would absorb best. We obtained 10ml of 0. 0040M KMnO4, and using a graduated 1. 0-ml pipette and a pipetting bulb, transferred 1. 00ml of it into a 25. 0-ml volumetric flask. We filled the flask half full with deionized water, and added 1. 0ml of 3. 0M H2SO4. After mixing the contents, we filled the flask completely with deionized water and mixed them again. After the sample solution was prepared, we calibrated a spectrophotometer using a blank solution; in this experiment, deionized water was used for the bla nk solution because H2SO4 is transparent in the visible region. For measuring the absorbance of KMnO4, first we selected a wavelength, and placed a cuvette containing blank solution, then replaced it with the other cuvette containing the prepared KMnO4 solution. The absorbance was measured at the wavelengths between 360nm and 660nm, and each time a new wavelength was selected, the spectrophotometer was recalibrated. After all the absorbance values were measured, we plotted the absorbance data versus the wavelength to determine ? max which was used for the remainder of the experiment. 2. Standard Absorbance Curve: For the second part of this experiment, we examined the effect of varying the concentration on the absorbance. Five differently concentrated KMnO4 solutions were prepared for this part. For each 25. 00ml sample, 1. 00ml, 0. 80ml, 0. 60ml, 0. 40ml, and 0. 0ml of 0. 0040M KMnO4, 1. 0ml of 3. 0M H2SO4, and deionized water were added. The concentration of each solution was calculated using the dilution equation, M1V1 = M2V2. After a sample was prepared, we set the spectrophotometer to the ? max discovered in first part, calibrated using the blank, and then examined the absorbance of the sample. After all the findings were examined, we m ade a plot of the absorbance versus concentration. The molar extinction coefficient could be calculated using the Beer’s Law and the measured results. The inside diameter of the cuvette (path length) was measured with calipers. 3. Concentration of an Unknown: In the last part, we determined the concentration of unknown solution using the results (the path length and the extinction coefficient) determined in the second part. We obtained a solution of KMnO4 of unknown concentration. We followed the same procedure as for the second part to dilute the unknown solution; added KMnO4, H2SO4, and deionized water to make 25. 00ml sample, and calibrated the instrument with the blank solution at the ? max, and then measured the absorbance. The concentration of the unknown before it was diluted could be determined using the dilution equation in a reverse way. Results Discussion 1. Maximum Absorbance Wavelength: In part 1, we determined the sample’s absorbance spectrum to find the wavelength (? max) at which KMnO4 absorbs best. The absorbance data measured in this part is shown in Table 1, and Figure 1 is the absorbance spectrum constructed by plotting A vs ?.

Standard Absorbance Curve: In part 2, we examined the effect of varying the concentration on the absorbance. We prepared five differently concentrated solutions (the higher concentrated solution appeared darker pink-violet), and using dilution equation, the concentrations were calculated. Figure 2: Color of permanganate in different concentrated solution The calculated concentration and the measured absorbance of each solution are summarized in Table 2. Table 2: Data for Standard Absorbance Curve Volume (ml)Concentration (M)Absorbance 1. 001. 6 x 10-40. 320 0. 801. 3 x 10-40. 252 0. 609. 6 x 10-50. 185 0. 406. 4 x 10-50. 122 0. 203. 2 x 10-50. 057 As shown in Table 2, when concentration decreased, the absorbance value also decreased. A plot of the absorbance verses concentration (Figure 4) resulted a straight line, and according to the equation (3), the Beer’s Law, we knew that the slope(2036. 563) of the line equals ? l. The path length(l) of the cuvette was measured to be 1. 18cm, and the extinction coefficient(? ) at 530nm was calculated to be 1. x 103; The molar extinction coefficient varies with the wavelength of light used in the measurement. Figure 3: A plot of Absorbance vs. Concentration 3. Concentration of an Unknown: The concentration of the unknown (#15) solution was calculated using Beer’s Law and dilution equation. Table 3 shows the data gathered.

In part 1, the maximum wavelength of KMnO4 was found as 530nm. When MnO4- is dissolved in water, it appears pink-violet, and as shown in color wheel below, it absorbs primarily yellow-green light. (The color a substance appears to be is directly across the wheel from the color of light that substance has absorbed. ) The range of the wavelength of green-yellow light is between 495nm ~ 590nm, so the maximum wavelength measured (530nm) is reasonable. Figure 4: The Color Wheel The absorbance spectrum shows how the absorbance of light depends upon the wavelength of the light. The spectrum itself is a plot of absorbance vs. wavelength and is characterized by the wavelength (? max) at which the absorbance is the greatest. The value of ? max is important for several reasons. This wavelength is characteristic of each compound and provides information on the electronic structure of the analyte. In order to obtain the highest sensitivity and to minimize deviations from Beers Law, analytical measurements are made using light with a wavelength of ? max. In part 2, we observed that the absorbance was lower in less concentrated solution. Before the experiment was done, we expected that in lower concentrated solution, because fewer number of absorbing molecules would exist, so less light would be absorbed; the expectation was correct. As I mentioned above, the solution appears pink-violet because permanganate absorbs primarily green-yellow light. The pink-violet color was darker in higher concentrated solution as in figure 2, and it can be explained that more green-yellow light was absorbed, so the violet color appeared darker. In part 3, we measured the absorbance of diluted unknown KMnO4 solution to determine the concentration of it. I got the sample of unknown number 15. We’d already known the value of the path length and the extinction coefficient, so we could calculate the concentration using the Beer’s Law. The solution was diluted to 25ml, so, in order to determine the initial concentration of the unknown, we used the dilution equation in a reverse way. The absorbance of the unknown was similar to the absorbance of the known sample, so I expected that the concentration would be similar; the known concentration was 0. 0040M, and the unknown concentration determined to be 0. 0033M.

5 Strategies to Prepare for the ISEE and SSAT

5 Strategies to Prepare for the ISEE and SSAT If you are thinking of applying to a private school in the fall, its never too early to get started addressing items on the admissions checklist.  For example, in addition to beginning work on the application and the candidate’s and parents’ statements, the applicant can study for the ISEE or SSAT, which are the required admissions tests at most private schools for students in grades 5-12. While the scores on these tests will likely not, in and of themselves, make or break a candidate’s application, they are an important part of the application portfolio, along with the applicant’s grades, statement, and teachers’ recommendations. Check out this article for  more information about how the SSAT and ISEE are scored. Taking the test doesnt have to be a nightmare, and doesnt require expensive tutoring or prep sessions. Check out these simple ways in which you can best prepare for the ISEE or SSAT and for the work that lies ahead in private middle and high school: Tip #1: Take Timed Practice Tests The best strategy to prepare for test day is to take practice tests- whether you are taking the ISEE or SSAT (the schools you are applying to will let you know which test they prefer)- under timed conditions. By taking these tests, you will know which areas you need to work on, and you will feel more comfortable taking the tests when it counts.  It also can help you get more accustomed to what is expected and the strategies you need to really excel, like how much a wrong answer might affect your score and what you can do about it.  Here is an article with some strategies to prepare for the tests. Tip #2: Read as Much as You Can In addition to broadening your horizons, independent reading of high-quality books is the best preparation not only for the ISEE and SSAT but also for the complicated reading and writing that most college-preparatory private schools demand. Reading builds your understanding of the nuances of difficult texts and your vocabulary. If you are unsure about where to start, begin with the 10 most commonly read books in private high schools. While it’s not necessary to have read this whole list before applying to a private high school, reading a few of these titles will expand your mind and vocabulary and acquaint you with the kind of reading- and thinking- that lie ahead of you. By the way, it’s fine to read contemporary novels, but try to tackle a few of the classics as well. These are books that have withstood the test of time because they have broad appeal and are still relevant to today’s readers. Tip #3: Build Your Vocabulary as You Read The key to building your vocabulary, which will help you on the ISEE and SSAT and with reading, is to look up unfamiliar vocabulary words as you read. Try to use common word roots, such as â€Å"geo† for â€Å"earth† or â€Å"biblio† for â€Å"book† to expand your vocabulary more quickly. If you recognize these roots in words, you will be able to define words you didn’t realize that you knew. Some people suggest taking a quick crash course in Latin to better understand most root words.   Tip #4: Work on Remembering What you Read If you find that you are unable to remember what you read, you may not be reading at the right time. Try to avoid reading when you are tired or distracted. Avoid dimly lit or loud areas when trying to read. Try to pick the right time to read- when your concentration is at a maximum point- and try to mark up your text. Use a post-it note or highlighter to mark key passages, moments in the plot, or characters. Some students will also find it helpful to take notes on what theyve read, so they can go back and refer to key points later on.   Here are more tips about how to improve your recall of what you read. Tip #5: Don’t Save Your Studying until the Last Minute Its important to note that studying shouldnt be a once and done thing when it comes to preparing for your test. Get to know the sections of the test well in advance, and practice. Take online practice tests, write essays regularly, and find out where you need the most help. Waiting until the week before the ISEE or SSAT test date isnt going to give you any sort of benefit when it comes to excelling. Remember, if you wait until the last minute, you won’t be able to discover and improve your weaker areas.   Article edited by  Stacy Jagodowski

Juno Character Analysis Essay Example | Topics and Well Written Essays - 750 words

Juno Character Analysis - Essay Example As the film unfolds, the viewer sees that Juno is not a bad girl; she is a young woman dealing with something she is really too young to deal with, she struggles with her situation and uses humor to manage her emotions, and she makes the decision that she feels is best for everyone involved. Throughout the film, the viewer is continually reminded that, despite her pregnancy, Juno is just a teenage girl. She is young and this was not a planned or wanted pregnancy. She is dealing with a entirely new set of emotions that she is not accustomed too. In addition to dealing with the emotions related to her pregnancy, Juno was dealing with facing the feelings she had towards Paulie, the baby’s father. As Juno spends more time with Mark, the adoptive father, she gets confused over her feelings towards him, as well. Juno states the situation of her age best when talking to her father. After witnessing Mark confront Vanessa about not really wanting to have a baby, Juno is filled with emo tions she isn’t sure how to deal with. She is confused and not sure how to deal with her emotions even though she has decided to still allow Vanessa to adopt her baby. After taking a minute to herself to cry, she goes home. Her father asks her where she had been, and she responds by saying, â€Å"just out dealing with things way beyond my maturity level.† Although she is clearly using sarcasm to mask her emotions, her comment accurately reflects the situation. After making the decision to put her baby up for adoption, opposed to keeping the baby or having an abortion, Juno does not deter from this decision. Despite this, she struggles with her decision. Her initial decision to have an abortion is abandoned early. She then immediately decides to put the baby up for adoption, and then works on finding an adoptive family. Juno frequently uses sarcasm and humor to get through emotionally difficult situations. When Vanessa questions her determination to put her baby up for adoption, Juno responds by saying, â€Å"If I could just have the thing and give it to you now I totally would.† If taken out of the context of the movie, this comment would sound cold and uncaring, but it is simply Juno’s way of expressing her determination while maintaining emotional distance. She struggles with the idea of giving the baby up for adoption, but she maintains her humor to stay focused. She also uses her humor to draw attention to her situation. She jokes about the fact she is sixteen and pregnant in an effort to divert negative attention for the same reason. During one of her interactions with Vanessa, Vanessa questions her regarding whether or not her parents know where she is. She responds to Vanessa’s questioning by saying, â€Å"I’m already pregnant so what other shenanigans could I get into?† This breaks the tension by exposing the elephant in the room. Juno makes the decision that she feels is best for everyone involved; this includes her, Paulie, Vanessa, and the baby. Juno recognizes immediately that her and Paulie are not equipped to give the baby a good life. In addition to this inability, she recognizes that fact that neither of them wants to stop being teenagers and start being parents. Forcing themselves to take on a role that neither of t

Alexander Techinque Essay -- essays research papers

The Alexander Technique is not so much something you learn as something you unlearn. It is a method of releasing unwanted muscular tension throughout your body which has accumulated over many years of stressful living. This excess tension often starts in childhood and, if left unchecked, can give rise in later life to common ailments such as arthritis, neck and back pain, migraines, hypertension, sciatica, insomnia and even depression. Vast amounts of money are being spent on the treatment of these illnesses (to say nothing of the pain and discomfort that is endured by the sufferer), yet the number of patients continues to increase. With the right education, however, many people could be helped to understand the causes of their problems and be taught to help themselves, so that their aches and pains may either be relieved or avoided altogether. The Alexander Technique can help us to become aware of balance, posture and co-ordination while performing everyday actions. This brings into consciousness tensions throughout our body that have previously gone unnoticed, and it is these tensions which are very often the root cause of many common ailments. This is exactly what Frederick Matthias Alexander, the originator of the Technique, discovered when trying to get to the bottom of his own voice-related problem. When applying the Alexander Technique you will learn how to release unnecessary muscle tension. As most of this tension has built up very gradually over a number of yea...

Health Care Dysfunctions and their Solutions

The American health care system has been previously bragged as the most excellent around the world until the emergence and realization of its major dysfunctions. The increasing number of American people who still could not afford the high cost of the health care system as well as the obvious problems within the structure itself is concrete manifestations that the existing health care program is no longer working to the advantage of the people.In fact, the alarming reality of the escalating health care price and its apparent inaccessibility definitely comprise a valid predicament particularly dysfunctions in the health care system. In any dilemma, there are possible solutions and however difficult, concerned people including authorities and those belonging in the health care industry need to continue look for ways to address and eventually solve the system’s failures.This is because in doing so, the health care system’s objectives to advocate excellent health among peopl e, be accessible and for it to be at reasonable price will ultimately become a reality hence paving way for the rectification of health care dysfunctions. Hence, the said factors are what the readers will be able to learn from the topic of health care system ultimately paving the way for the essential understanding of its dysfunctions and needed solutions.Health Care System, an OverviewThrough a comparison of the different health care structures of a variety of countries, relevant survey results indicated the true nature of a high-quality and reasonable health care system. The pieces of information and ideas resulting from such studies have signified a clear assessment of the health care systems of the United States and several countries as regard concerns about its price, accessibility, quality and choice of people but most importantly the effectiveness of the system in creating good health among people (â€Å"The U. S. health Care System: Best in the World, or Just the Most Expen sive? †, 2001).Citing the statistical report by the World Health Organization on some 191 member countries, the global health body was able to create three major objectives which also serve as the factors to be considered for a country’s health care system to be considered as good and fair. These include the health care program’s promotion of good health hence â€Å"making the health status of the entire population as good as possible† (cited in â€Å"The U. S. health Care System: Best in the World, or Just the Most Expensive?† 2001).Responsiveness is also a requirement where the system needs to respond to people’s prospects of appropriate health management and the corresponding orientation by health care providers to their respective public. Health care system should also be rational or fair in its costs and financing thereby assuring the financial protection of people and wherein its costs determined and spread based from a client’s financial capacity (â€Å"The U. S. health Care System: Best in the World, or Just the Most Expensive?†, 2001).Hence, the health care system’s general and excellent characteristic could be best yet simply exemplified in a way that it should supposedly deal with failures concerning its price, worth, convenience and variety. Health Care Dysfunctions Failures in the health care system are already evident even for the past years. Citing the Census Bureau, Davidz (2007) reported that there were already close to 47 million Americans who were not insured or not part of the country’s health care system for at least the past two years.While the statistics is only around 15 percent of the overall American population, recent records have shown that the percentage is likely to increase taking into consideration the significant dysfunctions of the system. Davidz also mentioned an economist’s observation that health care malfunction is characterized by too expensive or unaffordable health care program. However, the author noted that a possible plan to make a program reasonably priced discourages the provision of health care as it will slash into the enormous, untaxed privileges offered to those belonging to the top structure of an organization (Davidz, 2007).In essence, this cost-related failure of health care is an essential element which needs to be resolved. A personal experience or observation proves this particular dysfunction. In the State of California alone, approximately seven million residents do not have health coverage or health care program. The number is regarded to be the country’s biggest uninsured public and that the uncontrollably increasing price has been noted to be the main detrimental factor which pressures the inexpensiveness of any health care.While the emergence of the so-called â€Å"year of health reform† in California guarantees change in the system, it is still unfortunate to note that other equally-impo rtant health care dysfunctions continue to be unaddressed. Aside from the failure of making the system affordable, other malfunctions include the need for the system to be of high quality, accessible and provider of different selections where a person has diversity in choosing what health care plan is best fitting (Smith, 2007).Meanwhile, the accessibility failure of the American heath care only proved that the country is the only developed nation, aside from South Africa, which fails to give such benefit to its people. In contrast, the government only provides a mixture of insurance coverage offered by private organizations which is determined according to one’s employment as well as some government-based health programs which cater to active and retired military personnel, handicapped and deprived citizens. Such dysfunction forms severe breach as far as the accessibility of the insurance coverage.Coupled this with the cost fiasco, more people eventually let go of their resp ective health care program (â€Å"The U. S. health Care System: Best in the World, or Just the Most Expensive? †, 2001). A research has also proven that Americans are provided with only half of the suggested and supposed health care. Such study was determined based from the rising proofs of quality-related dysfunction in the American health care system. This also showed that a health program does not ensure one from getting quality care (Napier, 2006).Additionally, the system only poses harm to patients because it fails to live up to what is expected and that extensive quality-related issues are manifested by the rising number of medical blunders. Such error is due to the fact that people are provided with the misleading notion of service quality instead of the needed clinical or medical quality (â€Å"American families deserve quality health care,† 2007). Solutions to Health Care Dysfunctions Possible solutions were already provided such as overhauling the system wher ein the new administration commits to make health care program carry a high cost tag (Feld, 2009).However, what are needed are concrete solutions which aim to finally get to the bottom of this issue. Specifically as regard the quality of the health care, medical blunders need to be avoided through correct diagnosis, surgery and medication. These can be particularly done by creating and implementing means to track such clinical mistakes which will make health providers liable for the blunder as well as also ensuring the best quality among medical personnel making them fit for their work (â€Å"American families deserve quality health care,† 2007).As for the high cost, there is a need to limit the price of medical technologies, services and medication thereby ensuring the benefit of both the health care providers and clients. Aside from private-based health programs, government-initiated plans need to be more diverse offering easier access to almost sectors of the society such as children (Davidz, 2007). Finally, giving people with free choice of suitable health care program and provider will be another significant step to completely address, if not resolve the problem.Conclusion A nation’s health care system is expected to be free of dysfunctions in order to attain the good well-being of people. While failures in the system are inevitable, what is important and required are that the needed solutions are clearly identified and effectively implemented.References Davidz, E. (2007).
