Heats Of Dilution

Heats of solution and heats of dilution of lithium chlorate in water and dioxane–water mixtures have been determined experimentally. From these data apparent molal heat content, ΦL, and relative partial molal heat contents of solvent, [Formula: see text] and of solute [Formula: see text] have been calculated. The values of ΔG0, ΔH0, and ΔS0are also calculated.

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.

Heats of solution in 3.83N HF have been measured for zirconium metal and for five zirconium hydrides to evaluate the following heats of formation AHf0298: ZrH2 -39.7, ZrH1.85 -38.2, ZrH1.70. -34.7, ZrH1.43 -30.05, ZrH1.23 -25.3 kcal/mole hydride. A review of heat capacity and entropy data for zirconium hydrides has enabled a good correlation to be made between calorimetric and dissociation pressure studies, so that the effect of composition on all thermodynamic properties is established.
