Titrages acidimetriques par une methode de potentiometrie simplifiee : Emploi d'électrodes de zirconium et autres

Abstract

The proposed method differs from the classical “dead stop” procedure in that electrodes other than platinum electrodes are used. The simple set-up includes 2 indicating electrodes as cathodes, with a platinum counter electrode. With an applied potential, the method is essentially derivative potentiometry. Zirconium electrodes are given particular attention, and are shown to be particularly effective in the determination of very dilute strong acids. Antimony, bismuth, tungsten and tellurium electrodes are also discussed.
