When ferrous sulfate is heated strongly it undergoes decomposition to form ferric oxide as a main product accompanied by a change in color from green to yellow. The color of ferrous sulphate crystals are green and after heating, the color becomes white (pale yellow). On heating, ferrous sulphate crystals lose water and anhydrous ferrous sulphate (FeSO4) is formed. So their colour changes from light green to white. On further heating, anhydrous ferrous sulphate decomposes to form ferric oxide (Fe2O3), sulphur dioxide (SO2) and sulphur trioxide (SO3).
