Question

Give an equation to show how the following are made from their corresponding anhydrides.
(d) Sulphuric acid

Answer 1

The acidic anhydride of sulphuric acid ${\text{H}}_2{\text{SO}}_4$ is sulphur trioxide ${\text{SO}}_3$.
The chemical equation showing the preparation of sulphuric acid from sulphur trioxide can be given as,
${\text{SO}}_3+{\text{H}}_2\text{O}\to {\text{H}}_2{\text{SO}}_4$
