What role do air and moisture play in the rusting of iron?
Answer and explanation
Correct answer: Both oxygen in air and moisture are necessary for rusting.
Rusting of iron is an oxidation process that requires both oxygen from air and water or moisture. Moisture provides a thin water layer that supports electrochemical reactions, producing hydrated iron(III) oxide, called rust. Therefore, neither air alone nor moisture alone is considered sufficient for rusting.
