1.	Explain an activity to show the water of crystallisation in CuSO4 • 5H2O.
Answer» 1. Take a few crystals of copper sulphate in a dry test tube and heat the test tube. 2. We observe water droplets on the walls of the test tube and salt turns white. 3. Add 2 – 3 drops of water on the sample of copper sulphate obtained after heating. 4. We observe the blue colour of copper sulphate crystals is restored.
