Using tha data given below find out the strongest reducing agent.
`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

A

`Cl^(-)`

B

Cr

C

`Cr^(3+)`

D

`Mn^(2+)`

Text Solution

Verified by Experts

The correct Answer is:
B
Species having highest value of oxidation potential or least value of reduction potential is the strongest reducing agent. Therefore, `Cr(Cr to Cr^(3+) , E^(Theta)=0.74V)` is the strongest reducing agent.
