Finding number of ions
WebAug 25, 2024 · Because we know that Cl - ions have a charge of -1 and there are 3 Cl - ions in the compound, the Al ion must have a charge of +3 so that the overall charge of all the ions adds to 0. Thus, Al's oxidation number is +3 in this compound. 4 Assign an oxidation number of -2 to oxygen (with exceptions).
