“…Except for some scattered data on CdCl 2 (Tomaš et al, 2000(Tomaš et al, , 2004Višić and Mekjavić, 1996a), ZnCl 2 (Lewandowski, 1978;Višić and Mekjavić, 1984), RbSO 4 , ZnSO 4 (Esparza et al, 1993), and alkaline earth chlorides (Tasleem et al, 2004), data on γ ± are available primarily for 1:1 type electrolytes, particularly alkali halides (Table 5). The paucity of mean activity coefficient data for 2:1 type electrolytes in mixed solvents is associated with the complexity of these systems and the requirement for a priori knowledge of the speciation equilibria (Anderko et al, 2002) and the individual ionic association constants (Tomaš et al, 2000). For many 2:1 type electrolytes dissolved in mixed solvents, such information is presently not available.…”

Most of what is known about the environmental fate and transport of contaminants comes from studies of dilute, aqueous solutions. Theoretical and practical aspects of hydrophobic organic contaminants in aqueous mixtures of organic solvents are well developed, but relatively little attention has been paid to those situations where inorganic contaminants such as metals, water, and organic solvents occur simultaneously. The authors discuss changes in solution properties accompanying the addition of organic solvents. They review more than 500 references to available data on ion solvation, solubility, activity, acidity, pairing, and pH in electrolyte and electrolyte-free solvent mixtures and tabulate selected experimental values. Whenever available, equations developed to estimate these properties are given and their applications and limitations described. The implications of the progress in mixed-solvents solution chemistry on contaminant behavior and transport are described. Major limitations to the study of inorganic contamination in mixed solvents include the absence of complete and comprehensive data (e.g., type of ionic species, activity coefficients, solubility constants) that characterize solute and solvent properties in these mixtures and the indefinite number of possible solute and solvent combinations. The generation of models predicting such data from easily measured benchmark solute and solvent properties is a major challenge. The availability of such database and models may open the field for environmental engineers and soil scientists to study the basic chemical processes and mechanisms of metal contamination in complex multicomponent systems.

Equivalent conductivities of dilute solutions of calcium nitrate, cadmium nitrate, zinc nitrate, and calcium chloride (c < 0.0021 eq·dm−3) were measured in binary aqueous mixtures containing up to 70 wt % cosolvent (methanol, ethanol, and acetone) at 298.15 K ± 0.1. Data were treated by the Fuoss−Edelson equation, and its parameters, the limiting equivalent conductivity, Λ0, and the primary association constants, K 1 A, were evaluated. Variations in Walden products and K 1 A were interpreted in terms of ionic properties as well as solvent structure and dielectric constant.
