Oxidation Number. In I3- ion there is a 3 centre 4 electron bond between I2& I-ions, thus making the oxidation state of iodine as -1 as the oxidation states of I atoms in I2is taken as zero. Hence, the average oxidation number of I is . Hence, the average oxidation number of I is. It contains the polyatomic triiodide ion (I3–). In KI3, the oxidation no. In a KI3molecule, an atom of iodine forms a … cannot be fractional. However, O.N. Find out how to identify redox reactions using oxidation numbers. In almost all cases, oxygen atoms have oxidation numbers of -2. The compound is KI - which is correct because K = +1 and I = -1 so they balance. KI3is actually formed between K+ and I3-ions. 1. As a medication it is used to treat hyperthyroidism, in radiation emergencies, and to protect the thyroid gland when certain types of radiopharmaceuticals are used.
