Answer 2

$\huge\bf\fbox\orange{Answer:-}$

⭐The process of crystallization is used to purify a solid from its impurities.

⭐First of all, we take about 5 gram of impure sample of copper sulphate in a China dish.

⭐After that, we dissolve it in minimum amount of water then filter the impurities.

⭐Saturate the solution by heating that is when some solid starts evaporating.

⭐Then we cover the solution with filter paper and leave it undisturbed to cool slowly for a day.

⭐Hence, by this process we will obtain the crystals of copper sulphate in a China dish.
