Thermal decomposition of Ferrous Sulphate:

 

On heating green coloured ferrous sulphate crystals, reddish brown solid is left and smell of a gas having odour of burning sulphate is experienced.

2FeSO4(s)HeatReddish−Brown SolidFe2I3(s)+SO2(g)+SO3(g) 

In the above reaction, ferrous sulphate (FeSO4) decomposes to ferric oxide (Fe2O3).
