Some Basic Concepts Of Chemistry

\(\mathrm{SO}_{2} \mathrm{Cl}_{2}\) on reaction with excess of water results into acidic mixture

\(\mathrm{SO}_{2} \mathrm{Cl}_{2}+2 \mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{H}_{2} \mathrm{SO}_{4}+2 \mathrm{HCl}\)

16 moles of \(\mathrm{NaOH}\) is required for the complete neutralisation of the resultant acidic mixture. The number of moles of \(\mathrm{SO}_{2} \mathrm{Cl}_{2}\) used is :
