Which of the following is a set of reducing agents ?

A

`HNO_(3),Fe^(2+),f_(2)`

B

`F^(-),cI^(-),MnO_(4)^(-)`

C

`I^(-),Na,Fe^(2+)`

D

`Cr_(2)O_(7)^(2-),crO_(4)^(2-),Na`

Text Solution

Verified by Experts

The correct Answer is:
c
Since CI in `CIO^(-)` has an O.N of +1 which is higher than its lowest O.N of -1 and lower than its highest O.N of +5 therefore `CIO^(-)` can act as an oxidising as well as reducing agent
