Question

How crystallization is better than evaporation?​

Answer 1

Crystallisation is a process that separates a pure solid in the form of its crystals from a solution.

Crystallisation is better than evaporation because during Evaporation

• Some solids decompose or some, like sugar may get charred on heating to dryness.

• Some impurities may remain dissolved in the solution even after filtration which on evaporation contaminates the solid.

Answer 2

Explanation:

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.
