Hydrolysis of one mole of peroxodisulphuric acid produces

A

`2 mol`. Of sulphuric acid.

B

`2 mol`. Of peroxomono sulphuric acid.

C

`I mol`. Of sulphuric acid and `1 mol`. Of peroxomono sulphuric acid.

D

`1 mol`. Of sulphuric acid, `1 mol`. Of peroxomono sulphuric acid, and `1 mol`. Of hydrogen peroxide.

Text Solution

Verified by Experts

The correct Answer is:
C
Peroxodisulphuric acid `(H_(2) S_(2) O_(8))` or Marshall acid on partial hydrolysis gives `1 mol`.of peroxomonosulphuric acid `(H_(2) SO_(5))` or Caro's acid and `1 mol`. Of `H_(2) SO_(4)`.

Note : But complete hydrolysis of `H_(2) S_(2) O_(8)` gives `2 mol`. of `H_(2) SO_(4)` and `1 mol`. of `H_(2) O_(2)`.
`underset("Marshall acid") (H_(2) S_(2) O_(8)) + 2 H_(2) O rarr 2 H_(2) SO_(4) + H_(2) O_(2)`.
