Rust is an iron oxide, a usually red oxideformed by the redox reaction of iron and oxygen in the presence of water or air moisture. Several forms of rust are distinguishable both visually and by spectroscopy, and form under different circumstances. Rust consists of hydrated iron(III) oxides Fe2O.
The chemical formula for rust is Fe2O3. Rustis formed when iron reacts with oxygen in moist air. The following chemical equationrepresents the reaction: 4Fe + 3O2 → 2Fe2O3. Water is necessary for the oxidation reaction to occur and to facilitate transport of the electrons.
