A. Crystallisation is based on the difference in the solubilities of the compound and the impurities in a suitabl
Step-by-step solution
Correct Option is : (A) Crystallisation is based on the difference in the solubilities of the compound and the impurities in a suitable solvent. The impure compound is dissolved in a solvent in which it is sparingly soluble at room temperature but appreciably soluble at higher temperature. The solution is concentrated to get a nearly saturated solution. On cooling the solution, pure compound crystallises out and is removed by filtration.
