Question

How can we obtain pure copper sulphate from an impure sample

Answer 1

hey mate here is ur 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.

Answer 2

We can obtain it from the process of Crystallisation Crystallization is the solidification of atoms or molecules into a highly structured form called a crystal. Usually, this refers to the slow precipitation of crystals from a solution of a substance. However, crystals can form from a pure melt or directly from deposition from the gas phase.
