Expert Answer
Dear Student,
 
The iron salt which is green in colour changes to brown colour with a burning sulphur odour is ferrous sulphate with a molecular formula of FeSO4
When a green iron salt is heated to give brown colour compound then the type of reaction is known as decomposition reaction. Iron sulphate decomposes to form ferric sulphate, sulphur dioxide and sulphur trioxide.
The chemical equation of decomposition reaction of FeSO4 is:
2FeSO4→Fe2O3+SO2+SO3
Thus, on heating green coloured ferrous sulphate crystals, a reddish brown solid is left out and the smell of a gas having the odour of burning sulphur is obtained.
