Iron oxide reaction

In magnetite, since Fe2+ and Fe3+ are on eight sides… It is disordered, and electrons can be transferred rapidly between iron's two oxidation states, so the ferric oxide solid has excellent electrical conductivity. Ferric oxide can be made by heating iron in steam or reducing ferric oxide by hydrogen at 400. Ferric oxide is used as a pigment and polish. Magnetic iron oxide can manufacture sound recording, videotape, and telecommunications equipment. 1. Iron dioxide is water-soluble acid oxide. It can react with water and alkali. Iron oxide (Fe2O3) is a reddish brown powder in hematite, commonly known as iron red, which can be used as a paint pigment, and is a metal oxide and acid reaction. Fe2O3 + 6HCl=2FeCl3+3H2O. Ferrous oxide (FeO) is a black powder, unstable, heated in air, and can be oxidized to Fe3O4, which reacts with acid (weakly oxidizing acid). FeO+2HCl==FeCl2+H2O. Ferric oxide (Fe3O4) is a magnetic black crystal that mostly exists in magnetite, commonly known as magnetic iron oxide; it is a complex oxide, 1/3 of which is Fe2+, 2/3 is Fe3+, Fe3O4 can be seen as a compound formed by FeO, Fe2O3. [Essence is Fe(FeO2)2, ferritic, ferritic salt] Iron trioxide is the acid anhydride of ferritic acid (H2FeO4) and has strong oxidation; ferritic acid is strong, but soluble in water will rapidly hydrolysis, so H2FeO4 in water is not acidic.
