Formation of Iron(III) Oxide

4Fe + 3O2 → 2Fe2O3

Aperçu

Iron reacts with oxygen to form iron(III) oxide, commonly known as rust. This oxidation process occurs slowly in the presence of moisture and air. When iron burns in pure oxygen, the reaction is rapid and spectacular, producing bright sparks.
