Answer:
Crystals
of copper sulphate are prepared by the method of crystallization. The
process is as follows. A cupful of water is
taken in a beaker. Few drops of dilute sulphuric acid are added to
this. The water is then heated and when it starts boiling, copper
sulphate powder is added with stirring. Copper sulphate powder should
be added on till the solution becomes saturated. It is then filtered
into a china dish and allowed to cool. The solution should be kept
undisturbed. Slowly, the crystals of copper sulphate separate out.
