Why is the crystallization technique considered better than simple evaporation to purify solids?

Expert Answer:

Crystallisation is better technique because-
Extent of purification in case of crystallisation technique is very high.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.The technique does not require complex apparatus setup for performing the purification.
