AlN, as can be observed from its components, is an ionic compound. The positive oxidation state is counting the total number of electrons which have had to be removed - starting from the element. I2 + I^- > I3^- There are a few exceptions to this rule: When oxygen is in its elemental state (O 2), its oxidation number is 0, as is the case for all elemental atoms. What will be the oxidation number of I in the Kl3 Get the answers you need, now! Class XI Chapter 8 – Redox Reactions Chemistry In KI3, the oxidation number (O.N.) of K is +1.Hence, the average oxidation number of I is - 1/3 However, O.N. Use what you’ve learned to:a. Therefore, the oxidation number of N in KNO3 is +5. Hence, in a KI 3 molecule, the O.N. The oxidation numbers for the atoms in potassium iodide (PI3)are: P+3 and I-1. of K is +1. To find the correct oxidation number for N in NO3- (the Nitrate ion), and each element in the ion, we use a few rules and some simple math. Hence, the average oxidation number of I is. In KI 3, the oxidation number (O.N.) Calculating Oxidation Numbers. However, O.N. cannot be fractional. No. Different ways of displaying oxidation numbers of ethanol and acetic acid.
