Question

How will you separate the crystals of copper sulphate which you have prepared in the laboratory?

Answer 1

To prepare copper sulphate crystals crystallization technique is applied.

• Take water in a beaker and add a few drops of dilute sulphuric acid (H₂SO₄) into it.
• Start boiling water and add copper sulphate (CuSO₄) powder to it while stirring it continuously.
• Keep on adding copper sulphate powder till the solution becomes saturated. As soon as the solution became saturated filter the solution in the china dish and allow it to cool.
• Keep the solution undisturbed. Slowly, you will observe the copper sulphate crystals separating out from the solution.

So, to separate the crystals of copper sulphate crystallization technique will be applied.
