Lab Experiment: Separation of a Mixture by Paper Chromatography

Paper Chromatography:
- technique for separating and identifying mixtures that are or can be colored.

In this experiment, we've became acquainted with paper chromatography.  There are 3 parts in this lab experiment, in part 1, we assemble a paper chromatography apparatus, which  tells us how to set up a paper chromatography.  In part 2, we examined chromatography results for a variety of food colorings.  In part 3, we separated two mixtures of these colorings and study the significance of the Rf (ratio of fronts) values.
