Separating dissolved solids – chromatography

Paper chromatography is a method for separating dissolved substances from one another. It is often used when the dissolved substances are colored, such as inks, food coloring and plant dyes. It works because some of the colored substances dissolve in the solvent better than others, so they travel up the paper. 1. What is the name of the results of a chromatography experiment? 2. Finish the sentence; How far a dye travels depends on how __________ it is in the solvent.
