Abstract

A procedure has been developed for a volumetric determination of sulfate in solutions containing iron(III), chloride, and bromide. A solution is passed through the hydrogen form of a cation exchange resin, the effluent is titrated for hydrogen and for halide ion, and the sulfate is calculated from these titrations. The procedure was successfully used for a determination of sulfur in a pyrite ore.

The complexing of iron(III) with sulfate was studied both spectrophotometrically and by an equilibrium ion-exchange distribution method. Association constants and extinction coefficients for the [...] and [...] complex ions were obtained from these studies.

Resistance measurements and a study of the effect of current flow were made on a redesigned sodium coulometer. A number of the liabilities inherent in a sodium coulometer were considered.

A literature survey was made on the behavior of clay, ion-exchange, and glass membranes in solutions of various ionic species. Glass-membrane electrodes were prepared from four types of glass. The sodium-ion response of these electrodes in various buffer solutions was determined by following the change in potential of a glass-membrane electrode--buffer solution--calomel electrode system caused by varying the sodium-ion concentration of the solution. Resistance measurements were made on some of the glass membranes.
