Question

Give two reasons why crystallization is better than simple evaporation

Answer 1

Answer:

Crystallization is better than simple evaporation as:

1. Sometimes the impurities also gets mixed up with the liquid when evaporating, which we don't get when crystallized.
2. Some substance may burn while evaporating which don't happen in crystallization.

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.
