Zusammenfassung

Die Fällungswärme einiger Metallsulfide wurde zur Analyse von Metallsalzlösungen benutzt. Schwefelwasserstoff diente als Fällungsmittel und im enthalpimetrischen System als Titrationsmittel. Kupfer(II), Cadmium(II), Quecksilber(II), Wismut(III) und Eisen(III) wurden allein und in Mischungen bestimmt. Alle Metalle ergaben im Enthalpigramm scharfe Endpunkte, so daß keine Extrapolierung notwendig war.

Summary

The heat of precipitation of some metal sulphides has been used to assay some metal salt solutions. The hydrogen sulphide has been used as the precipitant and in a enthalpimetric system as the titrant. The method has been used for the determination of Cu(II), Cd(II), Hg(II), Bi(III), Fe(III) in single salt solutions and in admixture with some other ions. All the metals gave sharp end points in the enthalpograms and extrapolation was not required.
