Answer 1

Answer:

Correct Answer: (b) it loses water of crystallisation

Explanation: When green coloured ferrous sulphate crystals are heated, the colour of the crystal changes because it loses water of crystallisation.

Answer 2

Answer:

b) it loses water of crystallisation

Explanation:

On heating, ferrous sulphate crystals lose water. So their colour changes from light green to white due to the formation of anhydrous ferrous sulphate (FeSO4). When ferrous sulphate is heated, it gives ferric oxide, sulphur dioxide and sulphur trioxide.
