Das anodische Verhalten des Zinns bei Selbstpassivierung

The anodic behaviour of tin in the case of auto-passivation The diagrams: electrochemical affinity(A): overvoltage (U) characterizing the behaviour of tin in the p_H range 4–14 occupy an intermediate position between the groups Ni, Co, Cu, and Ti, Zr, Nb, U. On passive tin the formation of a double layer electrode of the type sn|SnO₂|Sn(OH)₄ appears thermodynamically probable. The anodic Flade reference potential of tin, depending from the p_H value obeys the equation .
