Question

What happens when crystals of ferrous sulphate is heated in a dry boiling tube?
Write chemical equation for the chemical reaction taking place; also write any one
observation of the reaction​

Answer 1

When ferrous sulphate crystals are heated in a dry boiling tube, they undergo decomposition to form Fe2O3 along with the release of SO2 and SO3.

- The chemical reaction is given as follows:

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

- There will be 1 mole of SO2 and 1 mole of SO3 formed in this reaction.

- So the total no of moles of gaseous products released is Two (2)
