Answer:
Evaporate water from the copper sulphate solution so as to get a saturated solution. Cover the solution with a filter paper and leave it undisturbed at room temperature to cool slowly for a day. You will obtain the crystals ofcopper sulphate in the china dish. The crystallisation method is used to purify solids
