(a) Interpretation: The unbalanced oxidation and reduction half-reactions for the reaction Mn(s) + NO 3 − (aq) → Mn 2 + (aq) + NO 2 (g) should be written. Concept introduction: Oxidation is the loss of one or more electrons from a substance which is indicated by an increase in oxidation number and reduction is gain of one or more electrons from a substance which is indicated by a decrease in oxidation number. By comparing the oxidation number of an atom before and after a reaction, it can be predicted whether the reaction is oxidation or a reduction reaction. There are some rules for assigning oxidation numbers to atoms. In the elemental state, an atom has zero oxidation number. The oxidation number of monoatomic ions is equal to its charge In a polyatomic ion, atom usually has the same oxidation number as it has in the monoatomic ion. The sum of the oxidation number of polyatomic ions is equal to its net charge while zero for neutral compounds.
