摘要：

Solubility at 25A degrees C has been determined in the MSO4-H2O-Solv systems (M = Co, Cu, or Cd; Solv = dimethyl sulfoxide, dimethyl formamide, dimethyl acetamide, tetrahydrofuran, or dioxane) via the isothermal saturation method. Analysis of the solubility as function of the permittivity and donor power of solvents along with the information on the cations radius leads to the conclusion that ion-ion association dominates over solvation interactions in the studied systems.
