    Notizen: Abstract Conductance measurements at 25°C have been carried out on Pr4NBr, Bu4NBr,n-Pe4NPr, Pr4NI, Bu4NI,n-Pe4NI, Bu4NClO4, Bu4NBF4, and Bu4PClO4 in isobutyl alcohol and on Bu4NBr and Bu4NClO4 in isopentyl alcohol. The main purpose of the measurements was to investigate the effect of increased branching in the alkyl portion of the alcohol on both ionic mobilities and ionic association. Comparison is made with the two isodielectric solvents butanone andn-butyl alcohol. Branching appears to produce little change in ionic mobilities and approximately a 10% increase in association.

    Notizen: Abstract Precise limiting ionic conductance data are reported for the first time for the alkali metal and tetraalkylammonium ions in D2O at 10°C as well as similar data for the halate and perhalate ions in D2O and H2O at 10 and 25°C. Precise transference numbers by the moving-boundary method are also reported for KBr in D2O at 10°C and, as a check on earlier work, for KCl in D2O at 25°C. In general, the structural properties of the ions, as reflected in the temperature coefficient of the limiting ionic conductances, are enhanced in D2O compared to H2O, although the differences are often small.

    Notizen: Abstract Viscosities at 10 and 25°C and dielectric constants at 10°C are reported for ethanol-water mixtures. Precise transference numbers for KBr at 10°C were determined by the moving-boundary method for five solvent mixtures containing up to 20 mole % ethanol. Conductance measurements for the alkali halides and tetraalkylammonium bromides were carried out across the complete range of solvent composition at 25°C, but for the water-rich region only at 10°C. The resulting limiting ionic Walden products confirmed the conclusions arrived at from earlier measurements. The maxima occurring in the water-rich region cannot be attributed solely to a structure-breaking effect owing to the ionic size dependence which is in the wrong direction. The tetraalkylammonium ions in these mixtures do not exhibit an enhanced hydrophobic effect, nor do they appear to enhance structure of any kind. Rather, the addition of alcohol to an aqueous Bu4N+ solution merely reduces the magnitude of the hydrophobic effect, as illustrated by a steadily increasing Walden product in the water-rich region. A decrease in temperature has no effect on the Walden product for the Bu4N+ ion but increases the magnitude of the maxima for the alkali-metal and halide ions. These maxima are attributed to sorting of the solvent components by the ionic charge, due to an acid-base type interaction, so that the proportion of water in the ionic cospheres is greater than in the bulk solvents. The sorting effect is shown to be temperature independent. The oxyanions are shown to exhibit a behavior in these mixtures that cannot be identified at this time.

    Notizen: Abstract Precise conductance measurements are reported for potassiumm-benzenedisulfonate and ferricyanide, for calcium, strontium, barium, and manganese chloride, and for manganese and potassium sulfate in D2O at 25°C. Measurements were also carried out in water at 10 and 25°C for all the salts with the exception of K3Fe(CN)6 at 10°C. Two runs are reported for sodium sulfate in water at 25°C. Limiting conductances of these ions are discussed in terms of solvent structural effects. The association constant for MnSO4 is found to be the same in H2O and D2O.
