The voltammetric behaviour of the silver sulphide-silver electrode in pure ammoniacal-alkaline electrolytes as well as in the presence of sulphide and the complex cation [Ag(NH3)2]+ have been investigated. It has been found that the silver sulphide-silver electrode behaves slightly irreversibly in ammoniacal-alkaline solutions of sulphide. On the basis of the results obtained the use of the silver sulphide-silver electrode for constant-current bipotentiometric and biamperometric end-point detection techniques appears to be convenient in the argentometric determination of sulphide.

Das voltammetrische Verhalten der Silbersulfid-Silber-Elektrode wurde in Ammoniak und Natronlauge enthaltenden Lösungen, auch in Anwesenheit von Sulfid und von komplexem Kation [Ag(NH32]+, untersucht. Es wurde festgestellt, da\ sich die Silbersulfid-Silber-Elektrode in Sulfid enthaltenden Lösungen schwach irreversibel verhÄlt. Die gewonnenen Resultate zeigen die Möglichkeit, die genannte Elektrode zur bipotentiometrischen oder biamperometrischen Endpunktbestimmung bei der argentometrischen Sulfidbestimmung anzuwenden.
