Iron loss equation
WebFeb 12, 2024 · A classic example of the old definition of oxidation is when iron combines with oxygen to form iron oxide or rust. The iron is said to have oxidized into rust. The chemical reaction is: 2 Fe + O 2 → Fe 2 O 3. The iron metal is oxidized to form the iron oxide known as rust. Electrochemical reactions are great examples of oxidation reactions.

An important aspect of the use of some metals, particularly of iron, is the possibility of corrosion. It is estimated that about one-seventh of all iron production goes to replace the metal lost to corrosion. Rust is apparently a hydrated form of iron (III)oxide. The formula is approximately Fe 2 O 3 • 3 2 H 2 O, although the ...
