Equilibrium was approached both from over-and undersaturation, and the equilibration times extended from 3 to 90 days. The solubility of Ni(OH)2(c) in the pH range of approximately 7 to 11.3 was effectively modeled by including aqueous Ni2+ and NiOH+ species. Values of the logarithm of the thermodynamic equilibrium constants for the reactions [Ni(OH)2(c) ⇌ Ni2+ + 2OH-] and [Ni2+ + OH- ⇌ Ni(OH)+] were determined to be -16.1±0.1 and 5.65 ± 0.10, respectively. These data, in conjunction with Pitzer ion interaction parameters given in the literature, were used to model the reported solubilities of Ni(OH)2(c) in chloride, sodium acetate, and potassium chloride solutions. The model predictions for these systems were in excellent agreement with the experimental data from the literature.
