摘要

Densities and electrical conductivities were measured for the ternary systems NaCl–mannitol(C₆H₁₄O₆)–H₂O, KCl–glycine(NH₂CH₂COOH)–H₂O, KCl–mannitol–H₂O, and NaBr–mannitol–H₂O at 298.15 K. Densities of the binary systems KCl–H₂O, NaBr–H₂O, glycine–H₂O and conductivities of the binary system NaBr–H₂O at 298.15 K were also measured. The measured densities were used to check the predictions of the semi-ideal solution theory. A new approach for predicting the conductivity of ternary electrolyte−nonelectrolyte mixture solutions in terms of the properties of their binary solutions of equal water activity is presented and compared with the measured values. The results show that the semi-ideal solution theory can provide good predictions for the densities and conductivities of the tested ternary electrolyte−nonelectrolyte solutions from the properties of their binary subsystems.
