The Estimation of Chloride by Measuring the E. W. F. of a Silver, Silver Chloride, Chloride Ion Half Cell for the Purpose of Estimating H or Other Toxics
Abstract
A method for 1) determining the chloride concentration in an aqueous solution by measuring the potential of a cell composed of a reference half cell and a silver, silver chloride, chloride ion half cell, and 2) determining the H or HN3 by liberating chloride by hydrolysis or by oxidation and then estimating the chloride is described. The procedures used to liberate chloride from H which has been collected on silica gel or charcoal, or in diethyl phthalate or acidified potassium permanganate solution are outlined in detail. The effectiveness of these absorbents and solutions in removing H vapor from air is studied. Procedures are also given for the determination of HN3 using dithyl phthalate or 0.25 F nitric acid as bubbler liquid.
