Using tha data given below is reducing potenial.
`E_(Cr_2O_7^(2-)//Cr^(3+))^@`=1.33 V , `E_(Cl_2//Cl^-)^@`=1.36 V
`E_(MnO_4^(-)//Mn^(2+))^@`=1.51 V , `E_(Cr^(3+) // Cr)^@` =- 0.74 V
find out which of the following is the strongest oxidising agent.

A

`CI^(-)`

B

`Mn^(2+)`

C

Cr

D

`Cr^(3+)`

Text Solution

Verified by Experts

The correct Answer is:
c
Lower the `E^(@)` stronger is the reducing agent thus Cr is the strongest reducing agent
