Combined solubility of copper and zinc oxides in ammonia-ammonium solutions

Combined solubility of copper and zinc oxides in ammonia-ammonium solutions

The combined solubility of copper and zinc oxides was studied in ammonia-ammonium chloride solutions with mass fractions of ammonia of 2, 5, 10, 15, 20, and 25% and mass concentrations of ammonium chloride of 43.8, 110, 150, and 180 g/l (based on chloride ion) at 293.15, 303.15, 313.15, and 323.15 K...

Zusammenfassung:The combined solubility of copper and zinc oxides was studied in ammonia-ammonium chloride solutions with mass fractions of ammonia of 2, 5, 10, 15, 20, and 25% and mass concentrations of ammonium chloride of 43.8, 110, 150, and 180 g/l (based on chloride ion) at 293.15, 303.15, 313.15, and 323.15 K. A eutonic type equilibrium was established in the systems, and the complex ions were mutually salted out.
