During this reaction, the oxygen and water react with iron to form flakes of iron oxide hydrate on the metal surface. Unfortunately for homeowners, many metal household items are vulnerable to rust.

Acids dissolve it readily, and when hydrated, as is the case in water ... or less ammonia when first precipitated. The oxide upon a galvanized iron roof would of course be dissolved to a certain ...

Most transition elements react slowly with cold water, or not at all. Iron reacts with water and oxygen at room temperature to form hydrated iron(III) oxide, or rust.
