In the following reaction, which is the species being oxidized?
` 2Fe^(3+) ""_((aq)) +2I^(-) ""_((aq)) +2Fe_((aq))^(2+)`

A

`Fe^(3+)`

B

`I^(-)`

C

`I_(2)`

D

`Fe^(2+)`

Text Solution

Verified by Experts

The correct Answer is:
B
`2 overset(3+) Fe_((aq))+2I_((aq))^(-) tp underset(0 ) (I_(2 (aq)) +2 overset(+2) 2Fe_((aq))`
here O.N of I increases from -I in `I^(-)` to 0 `O_2` therefore `I^(-)` ions are oxidized to `I_2`
