Question

when a hot solution cool, impurities remain in the solution and do not form crystals. Suggest the reason for this. [explaining]​

Answer 1

Explanation:

If a saturated hot solution is allowed to cool, the solute is no longer soluble in the solvent and forms crystals of pure compound. Impurities are excluded from the growing crystals and the pure solid crystals can be separated from the dissolved impurities by filtration.
