Thin layer chromatography in the organic chemistry typically uses a glass plate coated with silica gel, which serves as the stationary phase. The mobile phase in the experiment is an organic solvent or mixture of organic solvents. The mobile phase pulls the organic material(s) being analyzed up the plate by dissolving them in the solution. So, the more something dissolves in the mobile phase the further up the plate it moves. The mobile phase in this experiment will involve which...
