What is observed when ferrous sulphate is heated continuously in a test tube.write the equation for it and name the type of reaction in this case.
2FeSo4--------> Fe2O3+ So2+ So3
There is a smell of rotten eggs
The green colour of FeSo4 changes in reddish brown color of Fe2O3.
It is a thermal decomposition reaction
• On heating ferrous sulphate the crystals lose water and turn light green. On further heating It decomposes to ferric oxide ( Fe2O3 ) , sulphur dioxide ( SO2 ) and sulphur trioxide ( SO3 ).
• Balanced equation :-
2FeSO4 ----> Fe2O3 + SO2 + SO3
• It is a decomposition reaction.
