Crystallisation

Vedclass · Answer

(B) Crystallisation is the process used to purify solids. It is a separation technique that separates a pure solid in the form of its crystals from a solution. To obtain pure copper sulphate from an impure sample,the sample is dissolved in a minimum amount of water. The solution is filtered to remove insoluble impurities. The solution is then heated to evaporate the solvent until a saturated solution is obtained. Finally,the solution is allowed to cool slowly without disturbance,which results in the formation of pure copper sulphate crystals.
