Question

principle of crystallisation

Answer 1

The principle behind the crystallisation is that the amount of solute that can be dissolved by a solvent increases with temperature. In crystallisation, the impure substance is dissolved in a suitable solvent to reach its nearly saturated solution at a temperature higher than the room temperature.
