Thermodynamics of Zn(Ⅱ) complex equilibrium in Zn(Ⅱ)-NH3-Cl--CO32--H2O system was studied by the double equilibrium method.Varying the concentration of ammonia and ammonium chloride, respectively, in range of 0~5mol/L, the equilibrium concentration of all the species in the system are calculated, and thermodynamic diagram are plotted.The absolute average errors between theoretic calculation and the experimental values of total concentration of zinc are analyzed.The absolute average error between them is 7.47 %.The critical data and the thermodynamic model are believable.
