Question

Name the product formed on strongly heating ferrous sulphate crystals. What type of chemical reaction occurs in this change?

Answer 1

Strong heating of ferrous sulphate (FeSO₄) crystals results in the formation of products such as ferric oxide (Fe₂O₃), Sulphur dioxide (SO₂), and sulphur trioxide (SO₃).

\[\ce{2FeSO4_{(s)} ->[\Delta] Fe2O3_{(s)} + SO2_{(g)} + SO3_{(g)}}\]

This change is a thermal decomposition reaction (a specific type of decomposition reaction), where a single reactant breaks down into simpler products when heated.
