.... That is, the electric potential (voltage) of the zinc electrode becomes more negative (relative to the iron). The dominant anodic reaction is now: Zn (electrode) → 2e - (electrode) + Zn 2+ (in electrolyte). Thus, the zinc electrode becomes the anode and corrodes, while most of the corrosion of the...
