Question

why is crystallization is better than simple evaporation ​

Answer 1

Answer:

Crystallisation technique for purification is better than evaporation because: ... Crystallisation does not require very high temperature conditions, there is no need to boil the solvent. In evaporation, we allow the solution to heat to make the solvent evaporate but this may degrade the solute into some another compound.

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.
