Question

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.​

Answer 1

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

Answer 2

• 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.
