What are the total oxidation numbers for atoms of K, O and Cl, respectively, in KClO3, potassium chlorate, used in fireworks? Different ways of displaying oxidation numbers of ethanol and acetic acid. If the molecule is neutral, all of the oxidation numbers have to add up to zero. You can always use the method I mentioned in the other post to determine this kind of "exception." Answer Save. This is particularly important in redox reactions where some atoms lose (are oxidised) and others gain (are reduced) electrons. The oxidation numbers must thus sum to zero. 2 Answers. Decomposition.
