Why crystallisation is better than evaporation?
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 sugar may get charred on heating to dryness like sugar.
•Some impurities may remain dissolved in the solution even after filtration which on evaporation contaminates the solid.
