Spots of MMs and Skittles dyes move on the paper
name: Chromatography of MMs and Skittles dyes
Various food dyes consist of various substances. When the side of the filter paper touches the water, it moves up the paper due to capillary action. The dyes are transferred by the water with different rates. The rate depends on solubility of the dyes in water and sorption of the dyes on the paper. If the dye is a mixture of different substances, they separate to different spots on the paper.
You may use other solvents (alcohol or something else) for this experiment.
