Abstract

Because present data on free energy of formation and solubility product constants of the metal sulfides are both inconsistent and based on very old experimental data, a new study using modern techniques is amply justified. Because metal sulfide precipitates are often colloidal and becasue the solubility of these sulfides is so low, ordinary physical and analytical methods are not applicable to a direct determination fo the solubility product constant. Therefore, a more reliable thermodynamic approach was undertaken in this study. The standard free energy of formation of silver and mercury sulfide was determined from electromotive force measurements of suitable galvanic cells, and the solubility product constants calculated from the free energy measurements. This study is part of a large program extending to other metal sulfides and to other thermodynamic properties.
