| Abstract: | Summary Electroanalytical End-Point Determination of Hydrolytic Precipitation Titrations of Sulphate and OxalateThe possibilities of application of biamperometric and bipotentiometric end-point determination by means of various indicator electrodes are described. Several titrants were used. Best results were obtained with quinhydrone electrodes. Interference levels of several anions were established. The lowest concentration of oxalate and sulphate that can be determined is 5×10–4M.
Zusammenfassung Die Anwendungsmöglichkeiten der biamperometrischen und bipotentiometrischen Endpunktbestimmung mittels verschiedener Indikatorelektroden wurden beschrieben. Es wurden einige Titranten benützt. Die besten Resultate wurden mit Chinhydronelektroden erhalten. Die störende Wirkung verschiedener Anionen wurde festgestellt. Die geringste bestimmbare Konzentration beider Anionen (Sulfat und Oxalat) ist 5·10–4M. |
