Oxidation States of Phosphorus Compounds The difference in oxidation states between nitrogen and phosphorus is less pronounced than between oxygen and sulfur. (a) HPO3 : (b) H3PO4 : (c) H3PO3 : (d) H5P3O10 . 1 answer. ; Park, J.S. The charring effect is the strongest for phosphate, decreases with decreasing oxidation state and becomes of minor importance for phosphine oxide.- (Hint: Oxides of formula M3O4 are examples of mixed valence compounds in which the metal ion is present in more .
