While Fe^(3+) is stable, Mn^(2+) is not ...

While `Fe^(3+)` is stable, `Mn^(2+)` is not stable in acid solution because.

A

`O_(2)` oxides `Mn^(2+)` to `Mn^(3+)`

B

`O_(2) ` oxidises both `Mn^(2+)` to `Mn^(3+)` and `Fe^(2+)` to `Fe^(3+)`

C

`FE^(3+)` oxidizes `H_(2)O` to `O_(2)`

D

`Mn^(3+)` oxidizes `H_(2)O` to `O_(2)`

Text Solution

Verified by Experts

Reaction of `M n^(3+)` with `H_2O` is sponteneous.

Redox reactions play a vital role in chemistry and biology. The values of standard redox potential (E^(@)) of two half-cells reactions decide which way the reaction is expected to proceed. A simple example is a Daniell cell in which zince goes into solution and copper gets deposited.
