An investigation of the formation constant of molecular silver chloride using ion exchange techniques.|nII.|pAn investigation of the rate of precipitation of silver sulfide by thioacetamide

Abstract

The first part of this work reports on the investigation of the formation constant of molecular silver chloride using ion exchange techniques. In order to determine the formation constant, it was necessary to develop a method of rinsing the sorbed molecular silver chloride from the resin. It was found that desorption with nitrobenzene would remove the sorbed molecular species. However, the formation constant was not calculated since the nitrobenzene used contained hydrogen ion and chloride ion which removed silver ion as well as the molecular species. In the study of the formation of silver sulfide by the reaction between the thioacetamide and silver ion, it was found that the order of the reaction with respect to silver ion was zero at pH values 0.38 and 1.24. The zero order rate constants at these pH values are 1.66 x 10^-6 moles liters^-1 sec^-1 and 9.16 x 10^-6 moles liters^-1 sec^-1 respectively. Qualitative experiments indicate that there is a change in mechanism at a pH value of approximately two.
