(a) Ferrous sulphate.
(b) Decomposition reaction.
Anhydrous ferrous sulphate is formed when a ferrous sulphate crystal loses water. It decomposes into ferric oxide, sulphur dioxide, and sulphur trioxide.
(c) 2FeSO4→ Fe2O3 + SO2+ SO3
When a green iron salt is heated strongly, its colour finally changes to brown and odour of burning sulphur is given out.
