Question

Hydrolysis of one mole of peroxydisulphuric acid produces:

• A. two moles of sulphuric acid
• B. two moles of peroxymonosulphuric acid
• C. one mole of sulphuric acid and one mole of peroxymonosulphuric acid
• D. one mole of sulphuric acid, one mole of peroxymonosulphuric acid, and one mole of hydrogen peroxide

Answer 1

The correct option is C one mole of sulphuric acid and one mole of peroxymonosulphuric acid

Reaction:

$H_2{S}_2{O}_8+H_{2}O\to H_{2}S{O}_5+H_{2}S{O}_4$

So, one mole of sulphuric acid and one mole of peroxymonosulphuric acid is produced on the hydrolysis of one mole of peroxydisulphuric acid.
