WebCrystallization is a complex process through which solid forms, where the atoms or molecules are strongly packed into a structure known as a crystal. Attributes of the … WebCrystallization is the better method of separating the mixture than evaporation. This is because, on evaporation, some of the solid particles in mixture get decomposed leaving behind impurities whereas, in crystallization, pure crystals of solids are obtained. Why is crystallization used for purification?
