• A. Two moles of sulphuric acid
• B. Two moles of peroxomonosulphuric acid
• C. One mole of sulphuric acid and one mole of peroxomonosulphuric acid
• D. One mole of sulphuric acid, one mole peroxomonosulphuric acid and one mole of hydrogen peroxide

Answer 1

The correct option is C One mole of sulphuric acid and one mole of peroxomonosulphuric acid

Partial hydrolysis:

Complete hydrolysis:
$\underset{\text{Peroxodisulphuric acid}}{H_2{S}_2{O}_8}+2H_{2}O\to 2H_{2}S{O}_4+H_2{O}_2$
