Expert Answer
Crystallization is a process that separates a pure solid in the form of its crystals from a solution.
The various steps of purification used for impure copper sulphate are:
1.Take some (approximately 5 g) impure sample of copper sulphate in a china dish.
2.Dissolve it in minimum amount of water and filter out the impurities.
3.Evaporate water from the copper sulphate solution so as to get a saturated solution.
4.Cover the solution with a filter paper and leave it undisturbed at room temperature to cool slowly for a day.
5.Then crystals of copper sulphate in the china dish are obtained.
