✦ Synopsis

Partial molar volumes at infinite dilution provide a convenient test of theoretical models of aqueous solutions. In this communication, previously published experimental results of the apparent molar volumes for NaCl, NaBr, LiCl, and CsBr at near-critical conditions were Ž extrapolated to infinite dilution. In the temperature range included in this study 550 to . 725 K, ionic association processes must be considered. Using recently proposed equilibrium constants for alkali halides included in this study, the extrapolations were corrected for ion-association effects. Partial molar volumes at infinite dilution for free ions and ion pairs are reported for each electrolyte.
