Recrystallization is a purification technique for solid compounds to perform recrystallization, an impure solid compound is mixed with hot solvent to form a saturated solution as this solution cools, the solubility of the compound decreases, and pure crystals grow from solution. The process of recrystallisation involves dissolution of the solid in an appropriate solvent at an elevated temperature and the subsequent re-formation of the crystals upon cooling, so that any impurities remain in the solution.
