1) The basic food colors you can buy are red, blue, green, and yellow. Think about what you know about colors and predict which of these might be a single colored compound and which ones might contain more than one. Write down your prediction. If you have the colors listed and want a purple color, what would you do? 2) Put the following chromatography solvents in order of polarity as a chromatography solvent: acetone, n-propanol, water, hexane, diethyl ether, methanol. Explain your order based on what you have learned in CHEM 120. 3) You will be doing chromatography with a mixture of n-propanol and water. Would it make sense to add hexane to this mixture to try and make it work better? Explain. 4) Two cars full of people took a day trip. Car A had a lot of little kids and stopped at lots of rest stops and gas stations to give them a break. Car B had just adults in it, and only stopped once. Of course Car B got to the destination first. Explain how this in an analogy for the paper chromatography you are doing in this experiment.
