The literature covered in this review includes recent developments which became available since the review by Roe (221) and continues through the literature reported in Chemical Abstracts through November 20,1967.Potentiometric titrations and potentiometry were reviewed by Banick (15), Gross and Murray (88), and Hilton (105). Acid-base titrations and pH measurements were reviewed by Bates (16), Hahn (91), and Wimer (281). Redox titrations were reviewed by Strickman (256) and Headridge, Pierce, and Anderson (96). Electrode sign conventions were briefly treated by Van Rysselberghe et al. (269).

“…Stability constants of complexes for reaction were collected from the literature [24–30] and equations for the temperature dependencies of the stability constants were estimated with the least square method. The Gibbs energy functions for the complexes were then formed using fitted temperature dependencies.…”

The aim of this study was to build a thermodynamic model to extrapolate the system NiSO4–(NH4)2SO4–NH3–H2O which exists in aqueous hydrogen reduction processes of nickel. These solutions are relatively concentrated, and the temperature for solution preparation and reduction stages might range from room temperature up to 180–200°C. Temperature has a great effect on solution equilibria and the equilibrium solubility of simple and complex crystalline salts such as sulphates and hydroxides known to exist in the system. In this work, the role of kinetics is recognized, but only equilibrium phenomena reconsidered. The main focus of the study was on the modeling of salt solubility. In cases of a process solution where the precipitation of solid crystalline salts is highly undesirable it is important to know the safe limits for a ‘clear solution’ to operate even if the kinetics are unfavorable. Relatively concentrated solutions are strongly non‐ideal and realistic calculations on solution equilibria necessitate the modeling of excess thermodynamic properties of these solutions. The excess model selected for aqueous species was Pitzer's ion‐interaction model and for the gas phase Tsonopoulos' model. Emphasis in data assessment was on the thermodynamic modeling of various binaries and ternaries to create a substantial database for the approximation of the quaternary system.
