On the basis of the following `E^(@)` values, the stongest oxidizing agent is `[Fe(CN)_(6)]^(4-) rarr [Fe(CN)_(6)]^(3-)+e^(-), E^(@) = -0.35 V`
`Fe^(2+) rarr Fe^(3+)+e^(-), E^(@) = -0.77 V`

A

`[Fe(CN)_(4)]^(-)`

B

`Fe^(2+)`

C

`Fe^(3+)`

D

`[Fe(CN)_(6)]^(3-)`

Text Solution

Verified by Experts

The correct Answer is:
C
Strongest oxidizing agent is the substance which is reduced most easily i.e., has the highest reduction potential Reduction potential s of `[Fe(CN)_(6)]^(3-)` and `Fe^(3+)` are `+0.35V` and `+0.77V` Thus `Fe^(3+)` is reduced most easily and hence is the stronger oxidising agent.
