Vedclass · Answer

(A) During the corrosion of $Fe$ (iron),the metal surface acts as an electrochemical cell.At the anodic site,$Fe$ undergoes oxidation: $Fe(s) \rightarrow Fe^{2+}(aq) + 2e^-$.The electrons released at the anodic site move through the metal to the cathodic site.At the cathodic site,these electrons are consumed by the reduction of oxygen in the presence of $H^+$ ions: $O_2(g) + 4H^+(aq) + 4e^- \rightarrow 2H_2O(l)$.Therefore,the electron movement is from the anodic site to the cathodic site.
