Question

what type of mixtures are separated by the technique of crystallisation?

Answer 1

By the technique of crystallization, pure solids are separated from impurities. For example, salt obtained from sea is separated from impurities; crystals of alum (Phitkari) are separated from impure samples.

Answer 2

Those heterogenous mixtures in which the particles of the solute is suspended in the solvent and has a considerable size.....they can be separated by the proceas of crystallization.....in it a heavy solute particle like potash alum is mixed in the solution so that its particle join to the older solute particle.....It makes them heavy and hence they settle down....
