Electrolytic conductance of lithium bromide in acetone and acetone-bromosuccinic acid solutions: Electrolytic conductance of lithium bromide in acetone and acetone-bromosuccinic acid solutions. Jones, Charles W.; Cunningham, Clarence M. (Oklahoma State Univ., Stillwater, Okla., USA). Adv. Chem. Ser., 155(Thermodyn. Behav. Electrolytes Mixed Solvents, Symp., 1975), 244-62 (English) 1976. CODEN: ADCSAJ. DOCUMENT TYPE: Journal CA Section: 68 (Phase Equilibriums, Chemical Equilibriums, and Solutions) The Fuoss-Onsager-Skinner equation satisfactorily describes the electrolytic conductance of LiBr in acetone. Values of 198.1 .+-. 0.9 .OMEGA.-1 cm2 equiv-1 and (3.3 .+-. 0.1) .times. 103 are established for .LAMBDA.0 and KA, resp., at 25.degree.; furthermore, a value of 2.53 .ANG. is obtained for the sum of the ionic radii (a). When bromosuccinic acid is added to 10-5N LiBr in acetone, there is a decrease in the specific conductance of LiBr rather than the increase that is obsd. at higher concns.In this experiment, several chemicals are used like 923-06-8 and 7550-35-8 As the concn. of bromosuccinic acid is increased, the values obtained for .LAMBDA.0 and KA decrease, while those for a increase when the bromosuccinic acid and acetone are considered to constitute a mixed solvent. These results do not permit any simple explanation. When bromosuccinic acid and acetone are considered a mixed solvent, the Fuoss-Onsager-Skinner theory does not describe the system. .
