2021-7-26€hat is the oxidation number of aluminum in Al OH 4? Each H supplies an oxidation number of +1, so the total for hydrogen is +4.This means that the total oxidation number of the (OH)4 is 4.If you look at the Na+, it has an oxidation number of 1+. There is no charge on the molecule, so the oxidation numbers HAVE to add to zero.

By assigning oxidation numbers, we can pick out the oxidation and reduction halves of the reaction. Aluminum is oxidized to Al 2 O 3 in this reaction, which means that Fe 2 O 3 must be the oxidizing agent. Conversely, Fe 2 O 3 is reduced to iron metal, which means that aluminum must be the reducing agent.
