The correct options are
A It is used to separate components of a mixture
B In this technique, rate of movement of components aids the separation of the constituents
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 substances that dissolve in the same solvent. In this technique, the rate of movement of the components aids the separation. 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.
