Study of Equilibria in the "CuCl2–H2O–NaOH" System by Potentiometric Titration.

Equilibrium processes in the "CuCl₂–H₂O–NaOH" system are studied with the consideration of the formation of low soluble phases of various compositions based on mathematical processing of experimental results from potentiometric titration using EQ-5 software. The values of instability constants of copper complex ions and dynamic equilibrium constants of copper low soluble compounds are calculated along with their stoichiometric compositions and regions of stable existence.
