On the basis of following `E^(@)` values , the strongest oxidising agent is
`[Fe(CN)_(6)]^(4-)to[Fe(CN)_(6)]^(3-)+e^(-)E^(@)=-0.35V`
`Fe^(2+)toFe^(3+)+e^(-) " " E^(@)=-0.77V`

Options

A. `[Fe(CN)_(6)]^(4-)`
B. `Fe^(2+)`
C. `Fe^(3+)`
D. `[Fe(CN)_(6)]^(3-)`

Answer

C

Explanation

Higher the reduction potential larger is its tendency to get reduced and hence stronger is reducing agent.
