The following reaction occurs in aqueous acid solution: NO₃^- + I^- $\rightarrow$ IO₃^- + NO₂ What is the oxidation state of iodine in IO₃^-?

Quizplus · Accepted Answer

Iodine in IO₃^- has a oxidation state of (+5) because it is combined with fluorine, a more electronegative element, which has an oxidation state of (-1) in the molecule. The sum of the oxidation states in a molecule must equal the overall charge, which is (-1) in this case. Therefore, iodine must have an oxidation state of (+5) to balance the overall charge of the molecule.
