Question

Chromatography is used to obtain the components of an impure solution of copper (II) sulphate in water.

• A. True
• B. False

Answer 1

The correct option is B False

Chromatography is not used to obtain the components of an impure solution of copper (II) sulphate $\left({\mathrm{CuSO}}_4\right)$ in water.

Crystallisation can be used to obtain pure crystals of copper (II) sulphate and separate it from the impure components present in it.

• Crystallisation: Crystallisation is a technique to purify an impure sample and obtain pure solid in the form of crystals from its solution.

Chromatography: The technique of separation and purification of the different coloured components of a mixture due to the difference in their extent of solubility in the solvent (water for separating the components of ink) used for chromatography.

Hence, the given statement is false.
