By the end of this lecture, learners should grasp the electrochemical nature of aqueous corrosion, understanding key processes like anodic and cathodic reactions, charge movement in the metal and solution, and the necessity of maintaining charge neutrality. Learners will comprehend the simultaneous occurrence of oxidation and reduction reactions on a corroding surface, where metal oxidation leads to corrosion. The terms 'anodic' and 'cathodic' reactions will be associated with oxidation and reduction, respectively, emphasizing wet corrosion as an electrochemical process allowing spatial separation of reactions on the metal surface. The lecture emphasizes the balance between anodic and cathodic reactions, with the slower process determining the corrosion rate.
