Liste de potentiels standard

La liste des potentiels standard, en volts, qui suit est relative à la tension obtenue avec l'électrode standard à hydrogène et est assemblée à partir de différents ouvrages [1],[2],[3],[4],[5],[6],[7],[8].

Les valeurs sont obtenues sous ces conditions :

  • température de 25 °C ;
  • concentration effective à 1 mol/L pour chaque espèce aqueuse ou pour chaque espèce dans un amalgame de mercure ;
  • pression partielle à 101,325 kPa (absolu) (1 atm ou 1,01325 bar) pour chaque réactif gazeux. Cette pression est utilisée, car la plupart des données disponibles l'utilisent au lieu de la plus moderne de 100 kPa ;
  • activité chimique de chaque substance pure, sous forme solide ou liquide, ou pour l'eau (comme solvant).

Le tableau peut être trié alphabétiquement en cliquant sur le bouton de tri.

Légende :

  • (s) : solide ;
  • (l) : liquide ;
  • (g) : gaz ;
  • (aq) : aqueux (défaut pour toutes les espèces ayant une charge électrique) ;
  • (Hg) : amalgame de mercure.
