Question

Crystallization is the better method then the evaporation? Justify your answer by giving two reasons

Answer 1

Crystallization is the process by which solution is formed into crystals and separated from solution. While evaporation is the conversion of solvent into vapors.
Now the reason of Crystallization being better than evaporation is
1. Some solids might decompose due to heat provided in evaporation
2. Some impurities may remain disolved in the solution even after filteration.

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.
