Analysis 1. Examine the structures of the FD&C Red No. 40‚ Blue No. 1 and Yellow No. 5 dyes. What are the similarities and differences in the structures of the three dyes? a. Red No. 40‚ Blue No. 1‚ Yellow No. 5 contain carbon rings and NaSO3. Additionally‚ Red No. 40 and Yellow No. 5 are very similar‚ as they both contain one nitrogen double bond‚ a hydroxyl group‚ and no ions. Blue No.1 contains nitrogen and chlorine ions and N(C2H5)CH2. 2. In the Introductory Activity‚ the developing solvents

obvious‚ making it easy to use. There are many other indicators that change color at different pH levels‚ and so are useful for different purposes. Many pigments found in nature can be quite effectively used as acid-base indicators. The purple eggplant peel‚ the dyes in the blueberries and the purple camote peel contain anthocyanins. These plant pigments produce definite colors in solutions of different acidity or basicity. Anthocyanins are also water soluble and have colors that are dependent upon the

CHAPTER I Problem and its Background Introduction: Nowadays‚ many families are suffering from poverty and health problems. Some of these health problems are caused by different chemicals that they inhale from the things around them and by different chemicals in products which can cause them problems such as skin irritations. One of those things is the fabric softener‚ so the researchers came up making an alternative fabric softener that is harmless to the health of the people‚ inexpensive

This experiment was designed in order to extract caffeine from coffee grounds. In order to do this‚ filtration and extraction techniques with solvents such as calcium carbonate‚ magnesium sulfate‚ and dichloromethane were used1. Decaffeination is something that’s used around the world‚ and there is much discussion on the different methods that can be used. In this case‚ using solvents and heat was the preferred method in order to extract the caffeine. Decaffeination is often used to in order to prevent

Separations: Chromatography of M&M and Ink Dyes Almost all substances we come into contact with on a daily basis are impure; that is‚ they are mixtures. Similarly‚ compounds synthesized in the chemical laboratory are rarely produced pure. As a result‚ a major focus of research in chemistry is designing methods of separating and identifying components of mixtures. Many separation methods rely on physical differences between the components of a mixture. For example‚ filtration takes advantage of substances
