Abstract

The behavior of silver sulfite-ammonium chloride solution in the presence of copper (I). The presence of chloride ions in the sulfite-ammonia solution of silver promotes the transformation of the lower complex amines and sulphites of silver to the highestIt is possible the calculation of equilibrium constants of reactions of crystalline copper chloride (I) with sulfite-ammonia solution of silver. The effect of excess ammonia and sulfite ion on the behavior of copper (I). When you type in the copper chloride-ammonium sulfite solution of silver occur following processes: deposition of AgCl, the restoration of silver chloride and its complex compounds of sulfite ion ammonia complexes of copper (I), copper ions (I) and crystalline CuCl.
