Question

write three advantage crystallization and over evaporation

Answer 1

Crystallization is the process of obtaining pure salts from solutions.
In the case of obtaining salt from sea water evaporation is commonly used,but while evaporation there is a chance of decomposition of some substances.Therefore crystallization has more advantage than evaporation.crystallisation requires less heat no decomposition occurs gives only pure substance as compared to evaporation Crystalization seperate as solid crystals and if we evaporated its being lost and both on heating.

Answer 2

Why crystallization is better than evaporation?

1. It occurs on the entire surface.
2. we get solid in the pure crystallized form.
3. The soluble impurities get removed in this process.
4. It doesn't require very high temperature conditions.
