Question

What is the oxidation state of iodine in KIO3

Answer 1

The (V) is actually refering to the oxidation number of the iodine in the iodate ion. As you can tell from the formula, KIO3 (V), one K+ ion has bonded with the iodate, so iodate has a charge of -1. This is an abstract idea and is not meant to imply that there is an I+5 ion inside the iodate ion.

Answer 2

Answer:+5

Explanation:

Since K is as an alkali metal thus it has +1 as it's oxidation number and that of Oxygen is -2 so let oxidation number of I be x then,

+1+x+(-2)×3=0

This gives x=+5
