Question

Select the statements that are right with respect to chromatography.

Options:

A . It is used to separate components of a mixture

B . In this technique, rate of movement of components is taken advantage of to separate the mixture

C . It is used to separate colours in a dye

D . It is used to separate drugs from blood.

Answer: Option A
:
A, B, C, and D
Chromatography is the technique used for the separation of those solutes that dissolve in the same solvent. The word chromatography was derived from a greek word 'kroma', which means colour.
In this technique, the rate of movement of the components is taken advantage of to separate them. The components are dissolved in a solvent and are made to move through an adsorbent solid. The component that is more soluble in the solvent, dissolves faster and gets separated faster in the medium.
The ink that we use has water as a solvent and a dye is dissolved in it. Through chromatography, it is possible to separate the dye from ink and also to separate drugs from blood.
