Abstract

Previous work in the field of potentiometric titrations using bismuth-mercury electrodes with ethylenediaminetetraacetic acid as the titrant have been largely reproduced. The bismuth amalgam electrode has been further developed to provide ease of preparation and maintenance and through improved techniques of cleaning to eliminate electrode poisoning effects. Various titrations have been studied to determine the solution conditions necessary for maximum end point breaks, good electrode poise, and rapid and steady equilibrium of the electrode. These conditions have been adapted to make the electrode suitable for use with automatic titration equipment and for the analysis of multicomponent mixtures.
