Rusting of iron is an example of which process?
Answer and explanation
Correct answer: Slow oxidation
Rusting is a slow chemical reaction in which iron reacts with oxygen in the presence of moisture, forming hydrated iron(III) oxide, commonly called rust. It is therefore an example of slow oxidation, so option B is correct. Evaporation and freezing are physical changes, while dissolving a precipitate does not describe the formation of rust or the reaction of iron with oxygen and water.
