Concept: Understanding Oxidation versus Reduction Concept: Rules for Oxidation Numbers Example: What is the oxidation number of each underlined element? Cl2 2nabr 2nacl br2 7. Positive Ions. Fe2O3 has 3 O atoms, for a total oxidation no of -6; the total oxidation state of the products must equal the total of reactants, so the total oxidation no of Fe2O3 is 0; this means the oxidation number for Fe must be +6/2 = +3 4Fe + 3O2 → 2Fe2O3 . Courts Ri Gov Jury Service, In most compounds, oxygen is in oxidation state -2, so to balance these and get a neutral product molecule, you need 2 Fe^3+ ions (for a total charge of 2×+3 = +6) and 3 O^2- ions (for a total charge of 3×-2 = -6), so the formula is Fe2O3. Oxidation States: -1 0 Reduction Half Reaction ... comparison to the same element's oxidation state on the product side, one can determine if the element is being reduced or oxidized.
