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^(3+)`

B

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

C

`[Fe(CN)_(6)^(4-)]`

D

`Fe^(2+)`

Text Solution

Verified by Experts

The correct Answer is:
a
`[Fe(CN)_(6)]^(3)+E^(-)rarr[Fe(CN)_(6)]^(4)`
`E^(2)+=0.35V`
`Fe^(3+)+E^(-)rarrFe^(2+), E^(@)=+0.77` v
higher +ve electrode potential stronger is the oxidising agent thus option (a) is correct
