The process of obtaining. Crystallization is a process by which a pure soluble substance separates out in the form of crystals from its hot and saturated solution on cooling. the process is employed in the separation of pure common salt from the impure common salt obtained from sea. The process of crystallisation is used to obtain crystals of a pure solid substance from the impure solid substance. impure copper sulphate powder can be purified by the process of crystallisation to obtain large crystals of pure copper sulphate.
