It is used to separate the components of a mixture when all the components are very similar in their properties. It is used to separate liquid-liquid mixtures.
(b) The advantages of chromatography are:
- A very small quantity of the substance can be separated.
- Components with very similar physical and chemical properties can be separated.
- It identifies the different constituents of a mixture.
- It also helps in quantitative estimation of the components of a mixture.
(c) The two applications of chromatography are:
- It is used to purify many industrial products.
