Select the statement(s) that refer to chromatography.
The correct options are
A It is used to separate components of a mixture.
B The basis of separation is the rate of movement of components.
C It is used to separate colours in a dye.
D It is used to separate drugs from blood.
Chromatography is the technique used for separation of those solutes that dissolve in the same solvent. 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 absorbent 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 form ink. It is also used to separate drugs from the blood.
