Studies on the Dead-stop Titration. III

Dead-stop Titration, Derivative Polarographic Titration, and Potentiometric Polarography of Halides on Argentometry with Two Platinum or Silver Electrodes

Abstract

It had been shown in the preceding paper, that hydrogen peroxide is an effective additive in polarization titration, in connection with neutralization titration with platinum electrodes. Examination of various additives in the determination of halogen ions by silver titration also indicates hydrogen peroxide to be effective. On the other hand, an additive is unnecessary when using a minute silver electrode. Silver titration of halogen ion with the use of platinum or silver electrode was carried out by the dead-stop and derivative polarographic titrations. Potentio-metric polarography was carried out to make some theoretical considerations on titration.
