Answer 2

Chromatography

Step-by-step 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.
