Answer:
Chromatography
Explanation:
Chromatography is a separation technique which is based on different affinity of components of a mixture towards separation substance.
When we place a mixture of ink on chromatography paper, then the mixture of ink will get separated based on affinity for the stationary phase (paper) if placed in a suitable solvent.
The ink that has more affinity for stationary phase then the solvent will move less while the other ink will move faster.
