Question

Hydrolysis of one mole of peroxodisulphuric acid produces 

(a) two moles of sulphuric acid 

(b) two moles of peroxomono sulphuric acid 

(c) one mole of sulphuric acid and one mole of peroxomono sulphuric acid 

(d) one mole of sulphuric acid, one mole of peroxomono sulphuric acid and one mole of hydrogen peroxide

Answer 1

The correct option (c) one mole of sulphuric acid and one mole of peroxomono sulphuric acid 

Explanation: 

Peroxodisulphuric acid (H₂S₂O₈) on complete hydrolysis give tryo moieo of H₂SO₄ aud one rnole of H₂O₂.

While on partial hydrolysis it gives one mole of peroxomonosulphuric acid and one mole of H₂SO₄ as follows :
