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)<sub>1.5</sub>Cl<sub>0.5</sub>. For a chloride concentration value of 4.0 molal, there are two cupric compounds, the hydroxychloride Cu(OH)<sub>1.5</sub>Cl<sub>0.5</sub> or the diammine chloride Cu(NH<sub>3</sub>)<sub>2</sub>Cl<sub>2</sub>, on which the solubility of Cu(II) depends, according to the temperature and the value of the ratio [NH<sub>3</sub>]<sub>Total</sub>/[Cu]<sub>Total</sub>.}, number={3}, journal={Revista de Metalurgia}, author={Limpo, J.
