Purification of a solid by recrystallisation depends upon the fact that different substances have different solubilities in different solvents

In the simplest case, the unwanted impurities are much more soluble than the desired compound. The impure sample is dissolved in the minimum volume of hot solvent to form a saturated solution, then as the solution cools slowly, crystals of the desired compound form and can be collected by filtration

The soluble impurities remain in cool solution and so pass through the filter paper with the solvent
