Explanation / Answer
Separation is posiible in the solvent in which the ink is soluble in.
Different inks have different properties. When the paper chromatography is placed in the solvent, the solvent begins to move up the paper. As the solvent rises, it dissolves the ink into its components. The farther the ink travels, the more it is attracted to the solvent.
The compound that are soluble in water are the most polar compounds, while the ink that is soluble in the alcohols are less polar comparatively.
This is due to the fact that, like dissolves like. Polar compounds are soluble in polar solvents.
