The standard reduction potentials `E^(@)` for `OCl^(-)//Cl^(-)` and for `Cl^(-)//1//2 Cl_(2)` are 0.86 V and `-1.10` volt respectively. The `E^(@)` value of `OCl^(-)//1//2 Cl_(2)` will be :

A

`+ 1.96 V`

B

`- 1.96 V`

C

`+ 0.24 V`

D

Text Solution

Verified by Experts

The correct Answer is:
D
`{:(OCl^(-)+H_(2)O+e^(-) rarr Cl^(-)+2OH^(-)" "E_(red)^(@)=0.86 V ),(" "Cl^(-) rarr 1/2 Cl_(2)+e^(-)" "E_("Oxi")^(@)=-1.10 V),(ulbar(OCl^(-)+H_(2)O rarr 1/2 Cl_(2) +2OH^(-) " "E^(@))=0.86+(-1.10)):}`
