Conductance of electrolytes in dipolar aprotic solvent mixtures. I. Conductance of lithium chloride in mixtures of methylethylketone and acetone with N,N-dimethylformamide at 25�C

Thermodynamic dissociation constants of benzoic and nitrobenzoic acids in binary mixtures of water with acetone and tetrahydrofuran at 25.degree.C

“…Conductance measurements were carried out using an autobalance precision bridge (Wyne Kerr, B641) working at 1592 Hz in the same way as detailed earlier (8). Two different cells with cell constants 0.876 and 1.111 ± 0.002 cm-1 were used.…”

Ionic association and conductances of sodium perchlorate in N,N-dimethylformamide + water and tetrahydrofuran + water at 298 K

“…The fraction boiling at 66.5 and 67.5 °C was collected. IV^V-Dimethylformamide was also from Merck (99.5 mass %), and its purification has been detailed elsewhere (12). NaC104 (reagent grade) was crystallized from a methanol + water mixture (1:1 by volume) and dried at 150 °C in a vacuum oven.…”

Conductivities and thermodynamic dissociation constants for chloroacetic acid in binary mixed solvent systems at 298.15 K

“…where n is the number of data points. All the symbols have been described in previous papers (10)(11)(12)(13)(14).…”

“…Chloroacetic acid (from Merck, extra pure) was recrystallized from ethanol + water, dried under vacuum over P205, and stored in a desiccator. The melting point of the acid was 60-62 °C. The solvents were the same as used in previous studies, and their purification has been detailed previously (10)(11)(12)(13)(14). The fractionally distilled solvents had specific conductivities within (1-3) X 10~® S-cnr1.…”

“…The density p, viscosity , and dielectric constant e values for solvent mixtures were taken from the literature (10)(11)(12)(13)(14). Other procedures were the same as detailed earlier (10)(11)(12)(13)(14).…”
