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-)` |

Answer» Correct Answer - 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. |
