Hydrogen Peroxide

Question

Hydrolysis of one mole of peroxodisulphuric acid produces

Moderate

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 of peroxomonosulphuric acid and one mole of hydrogen peroxide

Solution

One mole of peroxydisulphuric acid on hydrolysis produces 2moles of sulphuric acid & one mole of H₂O₂.
If you take 1:1 ratio of H₂S₂O₈ & 1mole of H₂O gives Sulphuric acid and peroxymono disulphuric acid
If you take 1:2 ratio of H₂S₂O₈ & H₂O then we will get 2:1 ratio of H₂SO₄ & H₂O₂.

$\underset{1 mole}{H_{2} S_{2} O_{8} \overset{H_{2} O}{\to}} 2 H_{2} {SO}_{4} + 1 H_{2} O_{2}$
