Why iron reacts with steam to give Fe3O4 not Fe2O3? Another similar question is : why does a strange compound like $\ce {Fe3O4}$ exist ? Why is Iron (plus one or two other metals) able to make an oxide containing the same element at two different oxidation states ?
Reaction of iron with steam - Chemistry Stack Exchange Actually, Fe3O4 has a crystal structure (an extended geometrically regular array) of Fe (III), Fe (II) and oxide ions in which the oxide ions exist in a cubic close packed pattern with the Fe (II) ions located at half of the octahedral sites and the Fe (III) ions distributed evenly between octrahedral and tetrahedral sites
Fe3O4 as a mixed oxide - Chemistry Stack Exchange Fe3O4 is a mixed oxide This compound can be formed by different chemical means Will mixing FeO and Fe2O3 at room temperature or at certain conditions form Fe3O4 ? Is there any possibilities ? And
How is the triferric tetroxide of iron possible? If oxygen has a valency of $-2$, $4$ of it would result in $-8$ But iron doesn't have a (variable) valency of anything that goes to $-8$ Then how is $\\ce{Fe3O4}$ possible?
