Oxidation state of in `Fe_(3)O_(4)` is

`3//2`

`4//5`

`5//4`

`8//3`

Text Solution

Verified by Experts

Let the oxidation state of Fe be x, Using the fact that oxidation state of oxygen is usually `-2` and the sum of all possible oxidation numbers is zero, we can proceed as follows:
`3x+overset(x-2)overset(Fe_(3)O_(4))(4(-2)=0)rArr 3x - 8 = 0`
`rArr 3x = 8 rArr x = 8//3`
