The Chemical Reaction That Causes Rust - ThoughtCo

2022-01-22 · Technically, it's iron oxide hydrate, because pure iron oxide isn't rust. Rust forms when iron or its alloys are exposed to moist air. The oxygen and water in air react with the metal to form the hydrated oxide. The familiar red form of rust is (Fe 2 O 3), but iron has other oxidation states, so it can form other colors of rust.
