Properties of iron oxides

Ferric oxide is a basic oxide but also a metal oxide. There are three common oxides of the element iron: FeO (ferrous oxide), Fe2O3 (ferric oxide), and Fe3O4 (ferric oxide). Iron dioxide (FeO2) is a dark green viscous oily liquid. The melting point is -25, and the boiling point is 170. It smells of burning. It is dissoluble in water. An aqueous solution is acidic. Ferrum dioxide chemical formula: FeO2, the high price of iron oxide, iron is +4 valence. Physical properties of iron dioxide: dark green viscous oily liquid. The melting point is -25, and the boiling point is 170. It smells of burning. It is dissoluble in water. An aqueous solution is acidic. Chemical properties of iron dioxide: 1, iron oxide is a water-soluble acid oxide that can react with water and alkali. FeO2 + H2O ==== H2FeO3FeO2 + NaOH ==== NaHFeO3FeO2 + 2NaOH ==== Na2FeO3 + H2O2 and FeO2 are oxidizing, which can oxidize the metal and other reducing agents (take elemental iron as an example): 3FeO2 + Fe ==== 2Fe2O33, FeO2 have weak reducing property: 3FeO2 + O3 ==== 3FeO34, FeO2 meet water disproportionation, generating ferric acid. 5, iron dioxide and hydrochloric acid release chlorine and… Let go of oxygen. FeO2+5HCl=Cl2+FeCl3+2H2O.
