Explanation:
Answer: when blue copper sulphate crystals are heated they lose water of crystallization and blue colour of cuso4 changes to white.
Copper sulphate crystals are blue in colour due to the presence of water of crystallization. The colour in only there because of the presence of water of crystallization.
When they are heated strongly anhydrous copper sulphate is formed that is white in colour(colorless). This is so because of removal of water of crystallization.
The reaction is given by,
