Oxidation number if iodine in IO(3)^(-),...

Oxidation number if iodine in `IO_(3)^(-), IO_(4)^(-),KI and I_(2)` respectively are

A

`– 1, – 1, 0, +1`

B

`+ 3, +5, + 7, 0`

C

`+ 5, + 7, – 1, 0`

D

`–1, – 5, –1, 0`

Text Solution

Verified by Experts

The correct Answer is:
C
`IO_(3)^(-) : x + 3 (-2)=-1`
`x -6 =- implies x =+5`
`IO_(4)^(-) : x + 4(-2) =-1`
`x-8=-1 implies x =+7`
`KI : 1 +x =0 implies x =-1`
`I_1 : 2x =0 implies x =0`
