Oxidation

Oxidation involves an increase in the oxidation number of an atom Reduction occurs when the oxidation number of an atom decreases According to this model CO 2 is reduced when it reacts with hydrogen because the oxidation number of the carbon decreases from +4 to +2 Hydrogen is oxidized in this reaction because its oxidation number increases from 0 to +1 Oxidation-Reduction Reactions
