The more positive the value of `E^(0)`, the greater is the tendency of the species to get reduced. Using the standard electrode potential of redox couples given below find out which of the following is the strongest oxidising agent.
`E^(0)` values:
`Fe^(3+)//Fe^(2+) = +0.77, I_(2)(s)//I^(-) = +0.54`,
`Cu^(2+)//Cu = +0.34, Ag^(+)//A = 0.80V`

A

`Fe^(3+)`

B

`I_2(s)`

C

`Cu^(2+)`

D

`Ag^+`

Text Solution

Verified by Experts

The correct Answer is:
D
`Ag^(+)|Ag` is most positive and therefore , `Ag^+` is the strongest oxidising agent .
