Summary

The suitability of nitroferroin as indicator in the titration of oxalic acid with ceric sulphate has been investigated. It has been found from a comparative study that nitroferroin serves the purpose more satisfactorily and advantageously than ferroin. The use of nitroferroin as indicator avoids the need for high temperature, catalyst, and removal of sulphate ions during the titration and permits a satisfactory titration in HCl, HClO4, and HNO3 media.

Zusammenfassung

Die Verwendung von Nitroferroin als Indicator bei der Titration von Oxalsäure mit Cer(IV)-sulfatlösung wird untersucht. Nitroferroin läßt sich für diesen Zweck vorteilhafter benutzen als Ferroin, da weder höhere Temperatur noch Katalysator erforderlich sind, Sulfationen nicht entfernt zu werden brauchen und die Titration in salz-, perchlor- oder schwefelsaurer Lögung befriedigend verläuft.
