The oxidation number of Fe in Fe3O4 is fractional. Why?

Expert Answer:

Fe3O4 contains Fe atoms of both +2 and +3 oxidation number. It is a stoichiometric mixture of Ferrous (FeO) and Ferric (Fe2O3) oxides combined  as FeO.Fe2O3. Therefore, the oxidation number found in such cases is average oxidation number.
