Webb1 apr. 2024 · Rusting of iron, black coating on silver and the green coating on copper are examples of corrosion. Fats and oils become rancid and their smell and taste change when they are oxidized. Antioxidants are substances that prevent oxidation. They are added to foods having fats and oils. Foods are kept in air tight containers to slow down oxidation. WebbSlow oxidation of organic matter often involves the attachment of oxygen. For example, from primary alcohol carbonic acid may be obtained in several stages (as long as it does not ignite): CH₃-CH₂-OH + [O] = CH₃COH + H₂O
