Why blue colour of copper sulphate crystals disappears on heating? |
|
Answer» Copper sulphate crystals contain water of crystallisaton. Water of crystallization is the fixed number of water molecules present in one formula unit of a compound. Copper sulphate crystal contains five water molecules in one formula unit. When we heat the copper sulphate crystals then this water is removed and the colour of crystals turn white. |
