Chloride complexes of copper

The purpose of this paper is to demonstrate the principles of automatic computation for simple and complex systems and to illustrate these by reference to the copper and sulphur systems both separately and combined. The same methods are applied to the delineation of the conditions under which various chloride complexes of copper will predominate as a function of chloride activity rather than pH. 

Figure 6. A diagram showing the proportions of various chloride complexes of copper calculated as a function of chloride activity for pH < 5, pE = 10, and copper ion activities less than about 10 6. Note that the cuprous complex CuCl32 is dominant at very high chloride activities. The calculation is based on a number of assumptions (see text) that are unlikely to be entirely valid chloride activities much greater than 100 cannot be achieved readily.
