✦ Synopsis

The apparent molar volume, #.. of cadmium chloride, cadmium bromide and cadmium iodide in aqueous dioxane (loo/,, 200/,, 3o"A,) at different temperatures and concentrations are estimated from the densities of the solutions measured by a hydrostatic balance. The 4, values vary linearly with square root of concentrations. Deviations in the slopes of q%, versus ,/C are observed at higher concentrations of the salt and #,,,, limiting apparent molar volume, have been interpreted in terms of solutesolvent interactions. The $ U. values varies with temperature and can be represented in the power series of temperature. Structure making/breaking capacity of the electrolyte is inferred from the sign of a2&/at2-values. _
