Editing Iron(III) oxide (section)

==Preparation==
Iron(III) oxide is a product of the oxidation of iron. It can be prepared in the laboratory by electrolyzing a solution of [[sodium bicarbonate]], an inert electrolyte, with an iron anode:
:{{chem2|4 Fe + 3 O2 + 2 H2O -> 4 FeO(OH)}}

The resulting hydrated iron(III) oxide, written here as {{chem2|FeO(OH)}}, dehydrates around {{val|200|u=degC}}.<ref name=Brauer>Handbook of Preparative Inorganic Chemistry, 2nd Ed. Edited by G. Brauer, Academic Press, 1963, NY. Vol. 1. p. 1661.</ref><ref name=Ullmann/>
