Abstract
The values of the partial molal volumes for NaI, Kl, Et4NCl, Bu4NI, and R4NBr (R=Me, Et, Pr, Bu, Am) at infinite dilution in ethanol between 233 and 313 K are reported. Using a method proposed by the authors, partial molar volumes are divided into their ionic constituents at all the temperatures investigated. The changes of the partial molar volumes with temperature are positive for cations and decrease with a decrease in the ionic size whereas those for halide ions are negative and practically independent of the ionic size. The various contributions to the partial molar volume were evaluated and their dependence on the ionic nature and temperature are discussed.
