For example, the rusting of iron begins with the oxidation of solid iron: Fe ( s) Fe 2 + ( aq) + 2 e The corresponding reduction reaction involves water: Web2,400. [Illustration from U of West Indies: link]. For an extension, ask students to design and perform other possible combinations. Most metals corrode, some more rapidly than others, depending on that environment. Waters from rivers, lakes, and especially groundwaters from wells have usually been in sufficiently long contact with carbonate-containing sediments to have been neutralized. Coastal regions are thus more susceptible to corrosion than areas further in land due to deposition of salt aerosols. indicator in the gel to change colour. Contact. Another way to prevent the corrosion of iron is to exclude oxygen and moisture from its surface with a protective coating. reduction of oxygen produces hydroxide ions. 1.
