The oxidation number for NO3, or nitrate, is -1. How to find oxidation numbers, and a brief introduction to oxidation-reduction (redox) reactions. -1. (. This also means that nitrogen’s oxidation number is +6. Oxidation State of (NO 3-) This result is an approximation, as it is not always possible to determine the exact oxidation numbers based on a molecular formula alone. the oxidation number of oxygen is, as usual, -2. A compound does not have an oxidation number. Usually, the oxidation number of oxygen in a compound is -2. The exception to this rule is with peroxide; in that case, the oxygen number would be -1.

The oxidation number is synonymous with the oxidation state. But with NO3. N. O 3.

If you are referring to the nitrate ion, NO3-, the oxidation number of oxygen would be O2- and nitrogen would be N5+. +3. What is the oxidation number of Ca(NO3)2?

Wiki User. The oxidation state of an atom is the charge of this atom after ionic approximation of its heteronuclear bonds. Determining oxidation numbers from the Lewis structure (Figure 1a) is even easier than deducing it … The three oxygen atoms have a combined oxidation of -6, corresponding to their electromagnetic charge and the lone nitrogen has a charge, or oxidation number, of +5. This is because oxygen always has an oxidation number of -2.
