Question

What is crytallisation. ?

Answer 1

Crystallization is the process of slow precipitation of solid crystals of a substance from a concentrated homogeneous solution. It is basically a separation method in which a substance is transferred from the liquid (i.e. solution) phase to the solid state. The substance is thus obtained in pure crystalline form and has no impurity. It is used by chemists for the purification of solid substances.

Answer 2

Crystallization is the solid liquid separation and purification technique in which the mass transfer occurs from the liquid solution to a pure solid crystalline phase. It is based on the difference in the solubilities of the compound and the impurities in a suitable solvent
