faqs-mcqs class 10 Chemical Reactions and Equations-Heating of ferrous sulphate gives which product?-158

Review

( A )  All of the above

( B )  Ferric oxide

( C )  Sulphur dioxide

( D )  Sulphur trioxide

Correct Answer

All of the above

Explanation

Heating of ferrous sulphate (FeSO₄) gives ferric oxide [Iron (III) oxide (Fe₂O₃), sulphur dioxide (SO₂) gas and sulphur trioxide (SO₃) gas.

2FeSO₄ + Heat → Fe₂O₃ + SO₂(g) + SO₃(g)

Since, here ferrous sulphate decomposes after heating, hence it is a Thermal Decomposition Reaction.
