Sulphuric acid can be prepared by ____ (electrolysis/hydrolysis) of sulphuryl chloride.

Solution

Sulphuryl chloride $({SO}_{2} {Cl}_{2})$ :
${SO}_{2} {Cl}_{2}$ on reacting with $H_{2} O$ gives sulphuric acid $(H_{2} {SO}_{4})$ .
${SO}_{2} {Cl}_{2} (aq) + 2 H_{2} O (aq) \to H_{2} {SO}_{4} (aq) + 2 HCl (aq) Sulphuryl water Sulphuric Hydrochloric acid chloride acid$
So, Sulphuric acid can be prepared by hydrolysis of sulphuryl chloride.
