| 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. |
