Answer:
Test tube X and Z.
Explanation:
Copper sulphate has 5 molecules of water in its crystal. It sformula is CuSO4.5H2O It is an inorganic solid compound , blue in colour due to the presence of water of crystallisation. When copper sulphate is heated , the water of crystallisation evaporates and it turns into a white solid from blue. Consequently, white coloured copper sulphate crystals are obtained.
The colour of copper sulphate in test tube X and Z is blue, which shows the presence of water of crystallisation.
