Q.

The principle of column chromatography is :

  1. A

    Differential adsorption of the substances on the solid phase.

  2. B

    Gravitational force

  3. C

    Differential absorption of the substances on the solid phase.

  4. D

    Capillary action.

Solution

In column chromatograph a solid adsorbent is packed in a column and a solution containing number of solute particles is allowed to flow down the column. The solute molecules get adsorbed on the surface of adsorbent. So it is differential adsorption of the substances on the solid phase.
