Question

What happens when crystal of ferrous sulphate is heated? Which type of reaction is it?

Answer 1

On heating, ferrous sulphate crystalslose water and anhydrous ferrous sulphate (FeSO4) is formed. So their colour changes from light green to white. On furtherheating, anhydrous ferrous sulphate decomposes to formferric oxide (Fe2O3), sulphur dioxide (SO2) and sulphur trioxide (SO3).It is decomposition reaction.
