Answer 1

Explanation:

On heating it looses water molecules and becomes anhydrous ferrous sulphate. ... Ferrous sulphate crystals which are in green colour decomposes to give Ferric oxide, sulphur dioxide and sulphur trioxide gas. 3. On further heating FeSO4 anhydrous changes to dark brown solid.

Answer 2

Explanation:

QUESTION:

What happens when ferrous sulphate crystals are heated in a dry boiling tube?

SOLUTION:

• On heating it looses water molecules and becomes anhydrous ferrous sulphate.
• Ferrous sulphate crystals which are in green colour decomposes to give Ferric oxide, sulphur dioxide and sulphur trioxide gas.
• On further heating FeSO4 anhydrous changes to dark brown solid.

2FeSO4 →(∆) Fe2O3+SO2+SO3
