Hoch zur Elektrochemie , Viertes Kapitel - Erweiterter Kurs I

Hier sind die wichtigsten Metalle in der Spannungsreihe aufgelistet. Man findet sie auch in jedem Tafelwerk, meist aber nicht so umfangreich. Umso weiter oben ein Metall in der Spannungsreihe steht, desto unedler ist es. Wenn ein Metall unedel ist, würde es für ein edleres oxidieren. Also merken: Lithium würde immer für Gold oxidieren, Silber nicht für Calcium
