$\huge\bf{Method}$

Chromatography is the method of separating the constituent colours of not only black colour but also of the liquid constituent 'dyes' from their main constituent 'ink' .
It is based on - difference in adsorption of the constituents in ink - on the surface of an adsorbent medium , e.g. - filter paper .

$\huge\bf{Process Explanation}$

● We have to place the ink spot containing different constituents [dyes] - on the filter paper .

● Then the filter paper is hung with its lower end completely dipped - in the solvent .

● The solvent flows over the ink spot and the constituents - dyes - separate out .
