Charge of fe3o4
Schikorr reaction – This reaction is to convert iron(II) hydroxide (Fe(OH)2) into iron(II, III) oxide (Fe3O4). Under anaerobic conditions, ferrous hydroxide (Fe(OH)2) undergoes oxidationwith water to form magnetite and molecular hydrogen. This process is explained by the Schikorr reaction. 3Fe(OH)2 → Fe3O4 + H2 … See more The above image describes the structure of the Iron (II, III) oxide.
