Solutions of LiAsF6 at 298.2 K were studied by audiofrequency conductance in the concentrations range .0001-.01 Mol/Cu dm and by radiofrequency ultrasonic absorption in the concentration range 0.05 - 0.5 mol/ cu dm. The solvents employed were mixtures of 4-butyrolactone with 2-methyl tetrahydrofuran varying in compositions from mole fractions X subscript BL = 0. 10 X subscript BL = 0.75. In dilute solutions the audiofrequency conductivity data yield ion association ...
Audiofrequency electrical conductivity data are reported in the solvent dimethylcarbonate (DMC) at 25 deg C in the concentration range 0.0001 to 1M for LiAsF6 and 0.0001 to 0.3M for LiClO4. From 0.0001 to approx. = 0.01M the data are interpreted by the Fuoss-Kraus triple-ions theory leading to the values of the ion pair formation constant Kp and triple ion formation constant KT. For the data at higher concentration, it is ...
Electrical conductance data in the concentration range .0001 to .01 for LiBF4 in 1,2-DME are interpreted by the Fuoss-Kraus theory yielding values of the ion-pairs and triple-ions formation constants. Complex dielectric permittivities for LiBF4 in 1,2-DME at 25 C in the frequency range 0.9-81 GHz are reported. The data are interpreted by two Debye relaxation processes, one for the solvent and one for the solute. The latter is interpreted as ...
Ultrasonic absorption data are reported in the frequency range 1-7 MHz and 10-300 MHz for the electrolytes LiAsF6 and LiBF4 at t=25 degrees C, in 2-methyltetrahydrofuran. The data can be described by a single Debye relaxation for LiAsF6 and by two Debye relaxation processes for LiFB4. The observed processes are interpreted by a multistep Eigen type dimerization process leading to contact quadrupoles. In the case of LiAsF6 the products are ...
