`H_(2)O_(2)` is manufactured these days

A

By the action of `H_2O_(4)` on `BaO_(2)`

B

By the action of `H_(2)SO_(4)` on `Na_(2)O_(2)`

C

By electrolysis of 50% `H_(2)SO_(4)`

D

By burning hydrogen in excess of oxygen

Text Solution

Verified by Experts

The correct Answer is:
C
Electrolysis of 50% sulphuric acid gives per disulphuric acid `(H_(2)S_(2)O_(8))` which on distillation yeilds 30% solution of hydrogen peroxide.
