Investigations have been carried out to determine the complex ion formation between cuprous chloride and hydrochloric acid and cuprous chloride and potassium chloride in the aqueous and solid phase. An indirect method to determine the concentration of the components in the solid phase was employed due to the highly oxidisable nature of cuprous ions. Rectangular curves were drawn. In the case of hydrochloric acid, complexes like H 2 CuCl 3 and H 3 CuCl 4 are formed in the liquid phase while H 2 CuCl 3 ; H 3 CuCl 4 are formed in the solid phase. For potassium chloride, complexes like K 3 CuCl 4 and K 2 CuCl 3 were found to exist in the aqueous phase and KCuCl 2 and K 2 CuCl 3 were obtained in the solid phase. The amount of cuprous chloride going into solution with increasing amount of KCl was found to be lesser for HCl under identical conditions.
