Q23 of 45 Page 55

Crystallisation method is used to get salt from sea water. Why is it so?

The salt present in sea water may contain impurities in dissolved form. Simple evaporation causes the water to evaporate, leaving the impurities with the salt. In crystallisation, pure solid is obtained in the form of crystals from a solution. So, crystallisation ensures the purity of the product obtained.
