Abstract

Solvent extraction techniques have been used to determine formation constants for molecular silver chloride and dichloro silver (I) ion in unsaturated aqueous solutions. Nitrobenzene was used to extract the molecular silver chloride from the aqueous silver chloride solution. The total concentration of silver in each phase was determined by radioassay techniques and related by an expression involving the equilibrium constants. The reciprocal of the distribution ratio times the activity of the chloride ion was plotted versus the activity of the chloride ion and portions of the curve were analyzed by the method of least squares to obtain values for the constants involved. The values obtained for K1, K2 and Kd were 1.96 X 103, 3.00 X 105, and 0.243 respectively. A second analysis of the experimental data was made by a least squares analysis of a plot of the logarithm of the reciprocal of the distribution ratio versus the logarithm of the activity of the chloride ion. The analyis was performed over the entire range of experimental points and the values obtained for K1, K2, and Kd were 1.62 X 103, 2.80 X 105, and 0.285 respectively.
