Role of hydrogen peroxide iin the following reaction is respectively.
`(i)" " H_(2)O_(2) +O_(3) rarr H_(2)O+ZO_(2)`
`(ii)" " H_(2)O_(2)+Ag_(2)Orarr Aag+H_(2)O+O_(2)`

A

oxidizing in (`I`) and reducing in (`II`)

B

reducing in (`I`) and oxidizing in (`II`)

C

reducing in (`I`) and (`II`)

D

oxidizing in (`I`) and (`II`)

Text Solution

Verified by Experts

The correct Answer is:
A
In the reaction,

Since `H_(2)O_(2)` oxidises, `O_(3)` into `O_(2)`, thus it behaves as an oxidising agent.
Further, in the reaction,

Here `H_(2)O_(2)` reduces `Ag_(2)O` into metallic silver `[Ag]` (as oxidation number is reducing from `+1` to `0`). Thus, `H_(2)O_(2)` behaves as a reducing agent.
