Question:

In a paper chromatography analysis, three pigments, A, B, and C, were dissolved in a solvent. A is slightly polar, B is highly polar, and C is moderately polar. List in order how these will appear on the surface of the chromatography strip starting from the applied spot at the origin line.

Paper Chromatography:

It is a technique used to separate the components of a mixture. In this technique, the mixture to be separated is spotted on a chromatography paper (called the stationary phase) and dipped in a solvent (called the mobile phase). The components of the mixture have varying extents of solubilities in the mobile phase. All the components move up the stationary phase with the solvent and get separated because of different solubility extents. The paper is dried to evaporate the solvent.
