What role does moisture play in the rusting of iron?
Answer and explanation
Correct answer: It accelerates rusting by providing a medium for ion movement.
Rusting is an electrochemical process that requires both oxygen and water. A thin layer of moisture allows ions to move, accelerating oxidation of iron and formation of rust. In contrast, moisture does not block oxygen; iron rusts faster in moist air than in dry air.
