Oxygen atoms combined with other elements in compounds have an oxidation number of -2 (except in peroxides), so each O atom in CO, Fe2O3, and CO2 has an oxidation number of -2. To balance the reduction part, add two H 2 O molecules on the reactant side and balance it on the product side by adding four OH ions such as. A weak acid solution consists of mostly ionized acid molecules C. The oxidation number of pure elements is 0 D. The limiting reactant is the reactant present in excess in a reaction 5. By balancing the charges: the oxidation number of carbon is +4. Consider the combustion of 1.0 mol propane gas (C3H) in excess oxygen in open atmosphere at 25 C. Since, the overall charge on the complex is 0, the sum of oxidation states of all elements in it should be equal to 0. x + 2(2) = 0 or, x = +4 Hence, the oxidation state of C in CO 2 is +4. It represents the number of electrons an atom gains or losses when bonded with other atom in a molecule. Each atom in a pure element has an oxidation number of zero. co3. Y. Zhu, C. Du, Z. Feng, Y.
