Short explanation
In the subtopic Corrosion and its prevention, this learning objective focuses on describe rusting as corrosion of iron. (Chemistry only). Within Using materials, students should explain this idea in the exact curriculum context rather than as an isolated fact. Approved keywords for this objective include chemistry only, corrosion, rusting, and iron. rusting means the process of corrosion specifically affecting iron, resulting in the formation of iron oxide. Avoid students often describe rusting as the corrosion of all metals, not just iron; instead emphasize that rusting specifically refers to the corrosion of iron. For exam answers, clearly describe the process of rusting as the corrosion of iron, emphasizing the role of oxygen and water.
