N2 - Titrimetry technique has been used for the first time to determine the oxidation state in complex refractory oxides containing iron, uranium, cerium, and other mixed valence cations. In particular, sodium molybdate (3Na2O-4MoO3), used as an oxidative solvent for metal oxides. Cerium (IV) sulfate solution which prepared with sulfuric acid was used as a titrant. The excess Ce(IV) is back titrated with Fe(II) standard solution with indicator ferroin. The mechanism and the results have been interpreted.
