C. One mole of sulphuric acid, one mole of peroxymonosulphuric acid.
D. One mole of sulphuric acid, one mole of peroxymono-sulphuric acid and one mole of hydrogen peroxide.

Answer 1

Correct Answer - C
`H_2 S_2 O_8 overset("Patially hydrolysis") rarr H_2 SO_5 + H_2 SO_4`
`H_2 S_2 O_8 + 2H_2 O overset("Complete hydrolysis")rarr 2H_2 SO_4 + H_2 O_2`.
