∙ 11y ago
Reductant Iodide (I-) can be oxidised to other (more postive) oxidation numders by loosing electrons to the oxidant. Depending on the oxidant's strength this can change to the following numbers:
0 (zero) in I2 , and +1, +2, +3, +4 (in hypoiodite IO-, iodite IO2-, iodate IO3-, periodate IO4- respectively)

How does the oxidation number change when an element is oxidized?
Oxidation means there's an increase in oxidation number. Reduction means there's a decrease in oxidation number.
Can the oxidation number of an element change?
Yes, it can. When the element loses electron, the oxidation number increases and when it gains electron, the oxidation number decreases.
