Abstract

Cupric solubility in the CuCl₂-NH₄Cl-NH₃-H₂O system for chloride concentrations lower than 4 molal in the temperature range 25-60 °C was studied. The experimental results show that for chloride concentration between 3.0 and 1.0 molal the cupric solubility is determined by the solubility of the cupric hydroxychloride Cu(OH)_1.5Cl_0.5. For a chloride concentration value of 4.0 molal, there are two cupric compounds, the hydroxychloride Cu(OH)_1.5Cl_0.5 or the diammine chloride Cu(NH₃)₂Cl₂, on which the solubility of Cu(II) depends, according to the temperature and the value of the ratio [NH₃]_Total/[Cu]_Total.
