Which of the following is a set of reducing agents ?A. `HNO_(3),Fe^(2+),F_(2)`B. `F,Cl^(-),MnO_(4)^(-)`C. `I^(-),Na,Fe^(2+)`D. `CrO_(7)^(2-),CrO_(4)^(2-),Na`

Answer» Correct Answer - C
`2I^(-)rarrI_(2)+2e^(-)`
`NararrNa^(+)+e^(-)`
`Fe^(2+)rarrFe^(3+)+e^(-)`
As `I^(-)`, Na and `Fe^(2+)` can easily lose one or more electrons, they are all good reducing agents.
