Dilute Solutions

Conductances of dilute solutions of potassium iodate in water and water–dioxane solutions, extending over the dielectric constant range from D = 78.54 to D = 29.71, have been measured over the concentration range from zero up to Ka < 0.2 at 25.00 °C. By applying the Fuoss–Onsager treatment to the data obtained, the association constants for the electrolyte in the various solvents, as well as å, the distance of closest approach of the ions, have been determined.

The conductance of dilute solutions of sulfamic acid in water-methanol, water-ethanol and water-isopropanol mixture were measured at 25 °C. The experimental data were processed using the Lee and Wheaton equation to evaluate the limiting conductance Λ0 and association constant Ka. The lowest dielectric constant for each type of water-alcohol mixture was about 20.

Molar Volumes

Apparent molar volumes for dilute solutions of NaClO4 and [Co(en)3] (ClO4)3 in D2O and H2O were measured by using a dilatometry technique at 278, 298 and 318 K. Comparison of limiting slopes with the Debye-Huckel predictions from the dielectric constant and compressibility of H2O and D2O is complicated by ion pairing. The apparent molar volumes for NaClO4 were less in D2O than in H2O. The complex [Co(en)3] (ClO4)3 when studied in D2O had its amine protons exchanged by deuterium; this did not allow a direct comparison of the apparent molar volumes of the protonated complex in each solvent system, but revealed a large isotope effect. The apparent molar volumes of the [Co(en)3] (ClO4)3 showed a much larger temperature dependence than that of NaClO4.
