Corrosion is the chemical or electrochemical degradation of metals after reaction with the environment. Rusting, the corrosion of iron, is an oxidation–reduction process that destroys iron objects left out in open, moist air and costs billions of dollars per year in maintenance, repair and replacement. With the Corrosion of Iron: Guided-Inquiry Activity—ChemTopic™ Lab Activity, investigate chemical additives, surface coatings and metal combinations that reduce or prevent the corrosion of iron with a standard test method.
