Answer: Paper chromatography using different solvents with a range of polarities as the mobile phase

Edwin Brock · Answer 2

chromatography using different solvents with a range of polarities as the mobile phase

Explanation:

Chromatography is a separation method in chemistry which involves the separation of

the components of a mixture by allowing a solution of the mixture in a mobile phase (mixture of solvents of varying polarities) to pass through a stationary phase having varying affinities for the various components of the mixture. The components of the mixture are separated as they pass through the stationary phase.

Ink is best separated using different solvents with a range of polarities as mobile phase. This aids the separation of the components on the stationary phase.
