Question

why is crystalization better than evaporation for the separation of mixture

Answer 1

Heya,

Answer to your question is:-

Crystallization is better than evaporation in mainly two ways, :

1. In evaporation, the solution needs to be at the boiling point of the solvent, the whole time. This may degrade the solute.

2. In crystallization, the crystals automatically throw away impurities to arrange themselves in a regular manner. Therefore, the degree of purity is higher than the solute left after evaporation.

HOPE THIS HELPS:-))

Answer 2

Why crystalization 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.
