• D. one mole of sulphuric acid, one mole of peroxomonosulphuric acid and one mole of hydrogen peroxide

Answer 1

Answer: (C)

$$\begin{gathered} \underset{\text{Peroxodi sulphuric acid}}{\text{HO}-{\text{SO}}_2-\text{O}-\text{O}-{\text{SO}}_2-\text{OH}}+{\text{H}}_2\text{O} \\ \to \underset{\begin{array}{c}\text{Sulphuric per mono sulphuric}\\ \text{acid}\end{array}}{{\text{HOSO}}_2\text{OH}+\text{HO}-\text{O}-{\text{SO}}_2\text{OH}} \end{gathered}$$
