Iron hydroxide to iron oxide
WebIron (III) oxide can be made to react with vinegar or iron (II) acetate can be oxidised. I chose the latter route. The first reaction therefore is the reaction of vinegar with iron (steel). Due to the reductive environment created by the hydrogen in solution, the reaction first yields iron (II) acetate, the lower oxidation state.

Iron hydroxide to iron oxide
Did you know?
WebIron (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: 4 Fe + 3 O 2 + 2 H 2 O → 4 FeO (OH) The resulting hydrated iron (III) oxide, written here as FeO (OH), dehydrates around 200 °C. [19] [20] Under anaerobic conditions, the iron(II) hydroxide can be oxidised by the protons of water to form magnetite (iron(II,III) oxide) and molecular hydrogen. This process is described by the Schikorr reaction: 3 Fe(OH)2 → Fe3O4 + H2 + 2 H2O Anions such as selenite and selenate can be easily adsorbed on the positively charged surface of i…
