Abstract
Mayer's theory gives a good representation of the apparent molal volume [Formula: see text] of sodium chloride in aqueous solution at 25 °C up to a concentration 0.4 molar. Representation of the relative apparent molal heat content [Formula: see text] is also satisfactory but over a smaller range of concentration. The shape of the [Formula: see text] curve is strongly influenced by the temperature dependence of the distance of closest approach of oppositely charged ions in the solution. Methods of evaluating this term are considered. The utility of Mayer's theory for the extrapolation of experimental data to infinite dilution is illustrated in the case of [Formula: see text] and of intermediate heats of dilution.Keywords
