2FeSo₄--->Fe₂O₃+So₂+So₃ ================================================== We know ferrus sulphate crystal is green in colour . When we hear the crystals it turns into a dirty-yellow anhydrous solid as it loses water of crystallization.When heated more the anhydrous material releases So₂ and So₃ and leaves a reddish-brown iron oxide.
