Answer:

First part- As the water moves upward along the filter paper strip, the different pigments present in the black ink separate out as different points. After drying the paper, there is a colored pattern on the strip.

Second part- Black ink is made up of different colored pigments, and chromatography separates it into its constituent components.

Explanation:

Plato

Chromatography is the separation used for the mixtures in a substance. After 2-3 hours, the ink starts moving with the mobile phase resulting in the separation of the different colored components of the ink.

What is chromatography?

Chromatography has been the analytical technique for mixture separation. When the ink on the strip is kept in contact with a mobile phase like liquids and water then after some time it has been noted that different colors of the ink start moving with the solvent.

This separation of the ink components can conclude that black ink is made by mixing various colored pigments that have their own retention factors that get separated when kept along the solvent or the mobile phase.

Therefore, ink chromatography is a separation technique of the mixtures.
