Volumes Of Mixing

The volumes of mixing (excess volumes) for dimethyl sulphoxide with carbon tetrachloride, chloroform, benzene, acetone, and water have been measured at 25.00� and 35.00� with a dilatometer. The values for the equimolar mixtures at 25.000 are -0.596, -0.112, -0.304, -0.511, and -0.944 cm3 mol-1 respectively. The results are compared with available density measurements on these systems and qualitatively compared with the corresponding acetone systems.

Volumes Of Mixing

Abstract Densities of molten AgBr-AX (A = Li, Na, K, Rb, Cs; X = Br or Cl), AgBr-AgCl, KBr-NaBr, KBr-CsBr, KCl-KBr, and KCl-CsBr mixtures have been measured at 0.5 mole fraction using the method of Archimedean displacement. The excess volumes of mixing are all positive, except for the AgBr-LiBr system. Attempts to relate the excess volumes of the binary AgBr-ABr systems to the second order conformal solution theory of Reiss, Katz, and Kleppa are unsuccessful, since V E is large even when the diameter difference parameter, δ12, is close to zero. However, the excess volumes of the reciprocal AgBr-ACl systems at 0.5 mole fraction are found, within experimental error, to have a linear dependence on δ12. The positive deviations from conformal solution theory which occur for the alkali halide mixtures have been interpreted in terms of non-Coulombic polarisation and van der Waals interactions.

Dielectric constant and density measurements of solutions of chloro-, bromo-, and iodo-benzene together with those of p-dichloro-, p-dibromo- and p-diiodo-benzene in carbon tetrachloride at 25� are given. Distortion and atomic polarization values for the polar solutes are estimated by a method proposed by B�ttcher; the values are compared with other estimates of PD and PA. To obtain quantitative information of atomic polarizations, using B�ttcher's method, greater precision than is usual in solution dielectric constant measurements would be required.
