Answer
Solution:
Crystals of copper sulphate are prepared using the crystallisation method, which is described as follows:
- Take a cupful of water in a beaker.
- Add a few drops of dilute sulphuric acid to this.
- Heat the water, and when it starts boiling, add copper sulphate powder while still stirring.
- Add the copper sulphate powder till the solution becomes saturated. Filter into a china dish and allow it to cool.
- The solution should be kept undisturbed. Slowly, the crystals of copper sulphate separate out.
