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