Using the data given below:
`E_(Cr_(2)O_(7)^(2-)|Cr^(3+))^(@)=1.33V E_(Cl_(2)|Cl^(-))^(@)=1.36V`
`E_(MnO_(4)^(-)|Mn^(2+))^(@)=1.51V E_(Cr^(3+)|Cr)=-0.74V`
Mark the strongest reducing agent.

A

`Cl^-`

B

`Cr`

C

`Cr^(3+)`

D

`Mn^(2+)`

Text Solution

Verified by Experts

The correct Answer is:
B

Lower the value of reduction potential , stronger is the reducing agent i.e., undergoes oxidation most easily.
`Cr to Cr^(3+) + 3e^(-)` (oxidation)
Hence, Cr is ther strongest reducing agent .
