Given
`E_(cr^(3+)//Cr)^(0)=-0.74 V, E_(MnO_(4)//Mn^(2+))^(0)=1.51 cm`
`E_(Cr_(2)O_(7)^(2-)//Cr^(3+))^(0)=1.33 V, E_(Cl//Cl^(-))^(0)=1.36 V`
Based on the data given above, strongest oxidising agent will be:

A

`MnO_(4)^(-)`

B

`Cl^(-)`

C

`Cr^(3+)`

D

`Mn^(2+)`

Text Solution

Verified by Experts

The correct Answer is:
D
`Mn^(2+)` is the strongest oxidising agent because it has highest reduction potential value .
