Electrometric titrations with two polarized second-order electrodes

Electrometric titrations at constant resistance with two polarized second-order electrodes are shown to be possible. The polarization curve of the silver/silver chloride electrode is investigated theoretically and experimentally in order to find the best conditions for chloride titrations.Directions are given for the preparation and manipulation, of electrodes which enable quick titrations with rather dilute standard solutions (up to 0.001N AgNO₃). The titration apparatus used and some practical applications of the amperometric titration are described.
