Questions – 1. a. Stationary phase- saddle point approximation. b. Mobile Phase- the part of the chromatographic system which carries the solutes through the stationary phase c. Analyte- a chemical substance that is the subject of a chemical analysis 2. Pure- Blue Pen, Blue Marker Mixed- Green Marker, Black pen, Red pen 3. Yes because for them to be chemically changed they could not switch back to there original colors and therefore it is done by physical means. 4. If a pure substance were to be identified by a piece of chromatography paper the paper would only show one band of color. 5. Different solvents are used for chromatography because different types of solvents will make the colors spread out more. 6. The possible reason behind this is that the colors do not have a specific order on which they can rise and therefore when one color is at the top it will stay ahead of the other color. 7. First off the forensic person could get samples from a Chevy and a Ford and see if one of their paints is a mixed color and if the painted chip is a mixed color it will determine which car it is. 8. A magnet could separate components in a mixture or boiling the component to get the different mixtures.
