Rust is hydrated iron (III) oxide (Fe 2 O 3 .xH 2 O). The rusting of iron is a chemical change because we cannot get back pure iron from rusted iron by reversing the conditions. Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture. Rust consists of hydrous iron(III) oxides (Fe2O3·nH2O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH)3), and is typically associated with the corrosion of refined iron. Given sufficient time, any iron mass, in the presence of water and oxygen, co… ossip optometry irvington
