The oxidation state of iodine in `HIO_4,H_3IO_5` and `H_5IO_6` are respectively

A

`+1, +3, +7`

B

`+7, +7, +3`

C

`+7, +7, +7`

D

`+7, +5, +3`

Text Solution

Verified by Experts

The correct Answer is:
C
Oxidation state of I in` HIO_4` is +7 as:
`1 + x + 4 (-2) = 0 implies x =+7`
Oxidation state of I in `H_3IO_5` is +7 as:
`3 + x + 5 (-2) = 0 implies x = +7`
Oxidation state of I in `H_5 IO_6` is +7 as :
`5 + x + 6 (-2) = 0 implies x = + 7`
