Why is rusting of iron considered an example of slow oxidation?
Answer and explanation
Correct answer: Iron is gradually oxidised in the presence of water and oxygen to form hydrated iron(III) oxide.
During rusting, iron is gradually oxidised in the presence of water and oxygen to form hydrated iron(III) oxide. Since the reaction occurs over a long time rather than instantly, it is called slow oxidation. Option B describes dissolution only, whereas rusting is a chemical change that forms a new substance.
