Experiment 7 Experiment 7 The partition of Organic acid between Water and Organic solvent Objectives Understand the partition of a solute between two immiscible solvents. Introduction A chemical analysis that is performed primarily with the aid of volumetric glassware (e.g., pipets, burets, volumetric flasks) is called a volumetric analysis. For a volumetric analysis procedure, a known quantity or a carefully measured amount of one substance reacts with a to-be-determined amount of another substance with the reaction occurring in aqueous solution. The volumes of all solutions are carefully measured with volumetric glassware. The known amount of the substance for an analysis is generally measured and available in two ways: 1. As a primary standard: An accurate mass (and thus, moles) of a solid substance is measured on a balance, dissolved in water, and then reacted with the substance being analyzed. 2. As a standard solution: A measured number of moles of substance is present in a measured volume of solution - a solution of known concentration, generally expressed as the molar concentration (or molarity) of the substance. A measured volume of the standard solution then reacts with the substance being analyzed. The reaction of the known substance with the substance to be analyzed, occurring in aqueous solution, is generally conducted by a titration procedure. The titration procedure required a buret to dispense a liquid, called the titrant, into a flask containing the analyte. A reaction is complete when stoichiometric amounts of the reacting substances are combined. In a titration this is the stoichiometric point. In this experiment the stoichiometric point for the acid-base titration is detected using a phenolphthalein indicator. Phenolphthalein is colorless in an acidic solution but pink in a basic solution. The point in the titration at which the phenolphthalein changes color is called the endpoint of the indicator. Indicators are selected so that the stoichiometric point in the titration coincides (at approximately the same pH) with the endpoint of the indicator.

These meat substitutes are often advertised as beneficial for the environment. But do the customers really like them? Read the following chatroom discussions about GreenBurger, a product using alternative-meat patties. (A) Olivia That's a firm NO! I tried one when I was a prep cook for Next Level Burgers...tasted awful, just like mashed peas gone to rot. (B) Smith I haven't tried them. I just don't see the point. They are heavily processed with more calories and sodium than meat and are more expensive too! Unless you are a strict vegetarian and eschew meat for ethical reasons, meat is surely a better deal. (C) Mika Not really. It tastes too much like actual meat. If I wanted to eat a dead cow, I would go for real burgers. Being vegan means I try to stick to plant food. But this is just not something that will ever interest me. (D) Thomas GreenBurger just tastes "beany" to me, so I think that whatever form it comes in, it works better in recipes that would usually contain beans, such as in a rice bowl (as ground meat substitute). That being said, I'm definitely a carnivore and prefer meat, but I don't see anything wrong with choosing one of the fakey- fakey meaty things once in a while-just for a change. (E) Rico I finally tried one last week. It didn't taste that bad, but I was surprised to find it had 40 more calories than the meat version! Isn't it supposed to be a healthy choice? (F) Linda I liked it fine. I did NOT like the price, though. Hopefully that will come down. I'm trying to eat less beef. (G) Ablo Yes! My whole family does. We've been mostly vegan 90% of the time for the last 6 years and we cannot thank GreenBurger enough! Especially when a burger craving hits...a GreenBurger does the trick. I've tried all kinds of vegan "burgers," and GreenBurgers are closer to what I'm looking for. In fact, I can have them every day-vegan or not! (H) Alexander Well, they taste good if you add plenty of spices and sauces. Good for you? No, not at all. They're highly processed and contain no vegetables. They also contain a very large amount of processed coconut oil, which is even worse than lard. It's a killer for sure if eaten regularly.

For the Vandana Shiva will never forget a lesson she learned at the age of 13. Her parents insisted that she should wear clothing made only of homespun cotton. One day, Vandana, having returned from a boarding school to her home, demanded a nylon dress, the fashion followed by her rich friends. Her mother agreed. “If that is what you want, of course you shall have it,” she said. “But remember, your nylon dress will help a rich man buy a bigger car. And the cotton that you wear will buy a poor family at least one meal.” Did she buy the nylon dress? Of course not! Maybe this experience led to her resolution to fight for social justice in her later years. Now 60, ever visiting Taiwan in 2010, Vandana's main concern these days is how to preserve Indian traditional crops. This is severely attacked by many global companies. They encourage farmers to grow so-called high-yielding crops; many farmers, therefore, turn to high-tech methods and depend on bioengineered seeds, chemical fertilizers and pesticides. As a result, hundreds of traditional crops are disappearing. Contrary to expectation, high-tech agriculture can not rescue Indians from starvation. Bioengineered seeds are expensive and cannot adapt to local conditions. Hundreds of Indian farmers have committed suicide during the past five he world ironment. ns in 1970. years because of failed harvests. But there is hope. Many farmers are returning to traditional methods promoted by Navdanya, an organization based in New Delhi that Vandana helped found 20 years ago.

It also helps local farmers form their own self-supporting organization and seed bank. nean? +明一 生能但奇 63

Some people want the tastiest food, while others desire the biggest return on their investments Before we make any final decisions, we are given a lot of choices to sort through? Most of us feel that the more choices we have, the happier we'll be, as we'll be better able to determine which is best for us. At least, that's what we used to think. Research now shows us that there is such a thing as having too many choices, and it's actually making us miserable.' In fact, an excess of choices can lead to dissatisfaction, depression, anxiety, self-blame, and 'fegret. This is because it paralyzes us and forces us to make decisions that go against our best interest. What's more, it results in a huge waste of time. American psychologist Barry Schwartz lays this all out in his book, The Paradox of Choice. He sheds light on the process by which we become less satisfied, which is the cost of having too many options. First, once we've made our pick, we imagine how we could have done better. This then nags at us, making us regret our imperfect decision Soon, we convince ourselves that the discarded options or even imaginary alternatives would have been better than what we settled on, which causes expectations to rise. We're not completely satisfied with the outcome of our decision, even if it's a good one. In the end, we are no longer able to experience pleasant surprises.

Your report should follow these guidelines, although you may choose how you present it: How to Write a Mathematics Report In writing your report, remember that you are writing up a mathematical story and so, like all good stories, it will need a beginning, a middle and an end. More formally, the main components of this writing style are: Introduction, Formulating the Problem, Solving the problem, Discussion of Results, and Conclusion. We will now consider some of the detail in each of these aspects. Introduction This is the beginning of the story. Give a brief explanation of what the problem is about what the goals of the report are and what will be presented. Assume that your reader does not know what the problem is about or how to solve it. Formulating the problem Translate the situation into a maths problem. Explain how you will begin to solve the problem and break it into simpler stages. Discuss any assumptions made. What quantities are variables and which values are fixed? You may use sub-headings if they assist you. Solving the Problem Show any calculations and mathematical reasoning that you use. (Assume that your reader does not know much maths). Do not show the same types of calculations repetitively. Just give one or two examples of a calculation and then put the rest of the results in a table. Use diagrams or graphs if they assist you. Make general remarks about what you observe in your calculation results and, possibly, why. You may want to criticise your work and go on to improve it in the next section. Explain what you will do next and why. Discussion of Results - Evaluate and Verify Summarise your results if necessary and refer to your mathematical reasoning. Justify procedures used. Interpret your results. First, are they reasonable or does something not look right and need further investigation or checking? Is there a decision to be made? Here is where you should present the decision-making process. Evaluate the strengths and limitations of your solutions. Conclusion Summarise your findings. Refer to the problem outlined in the introduction. Make sure that you answer the question that was asked. Make recommendations. No new material should be presented here.
