Kinetics and mechanism of corrosion of iron in phosphoric acid

WebTherefore, most transition metals are capable of forming different products in a combination reaction. Iron reacts with oxygen to form both iron (II) oxide and iron (III) oxide: 2Fe(s)+O2(g)→2FeO(s) 4Fe(s)+3O2(g)→2Fe2O3(s). This reaction is used to produce the bright flame generated by flares and some fireworks.
