The standard electrode potentials (E^(@)...

The standard electrode potentials `(E^(@)) " for " Ocl^(-)//Cl^(-) " and " Cl^(-)//(1)/(2) Cl_(2)` respectively are 0.94 V and `-1.36 V`. The `E^(@)` value for `Ocl^(-)// (1)/(2) Cl^(2)` will be:

A

`-0.42V`

B

`-2.20V`

C

`0.52V`

D

`1.04V`.

Text Solution

Verified by Experts

The correct Answer is:
A
`Cl^(-)rarr1//2Cl_(2)+ e^(-):E^(@)=-1.36V`
`Ocl^(-)+H_(2)O+e^(-)rarrCl^(-)+2OH^(-):E^(@)=+0.94V`
`Ocl^(-)+H_(2)Orarr1//2Cl_(2)+2OH^(-)`
