Question

Hydrolysis of 1 mol of peroxodisulphuric acid produces :

• A. 2 mol of sulphuric acid.
• B. 2 mol of peroxomono sulphuric acid.
• C. 1 mol of sulphuric acid and 1 mol of peroxomono sulphuric acid.
• D. 1 mol of sulphuric acid, 1 mol of peroxomono sulphuric acid, and 1 mol of hydrogen peroxide.

Answer 1

The correct option is C 1 mol of sulphuric acid and 1 mol of peroxomono sulphuric acid.

Peroxodisulphuric acid $\left(H_2{S}_2{O}_8\right)$ on partial hydrolysis gives 1 mol of peroxomonosulphuric acid and 1 mol of $H_{2}S{O}_4$.

Hence option C is correct.
