Question

The separation of the constituents of a mixture by column chromatography is based on the………….of the various components in the mixture.
A. differential extraction
B. differential adsorption
C. differential partition
D. differential retention

Answer 1

Correct Answer - B
Here the stationary phase is a suitable adsorbent packed in a column. The mixture to be separated is dissolved in a suitable solvent and the solution is poured on the top of the column of the adsorbent. The components are then eluted out by a suitable solvent (mobile phase). The weakly adsorbed component will be eluted more rapidly than a strongly adsorbed component.
