Preservation Chemistry
Submerged iron oxidizes via cathodic oxygen reduction:
Fe → Fe²⁺ + 2e⁻ (Anodic)
O₂ + 2H₂O + 4e⁻ → 4OH⁻ (Cathodic)
Attaching sacrificial anodes with lower electrochemical potential ($E^0$) forces the anode to oxidize preferentially, supplying electrons to cathodic protection boundaries on the ship hull.
