A Study of the Conductances of Some Uni-univalent Electrolytes in N,N-Dimethylacetamide at 25°

Conductance and Ionic Association of Imidazolium-Based Ionic Liquids inN,N-Dimethylacetamide

“…The specifications of used chemicals are summarized in Table . The specific conductivity, κ, of DMA was 2 × 10 –7 S·cm –1 at 298.15 K, which is in good agreement with available data. , …”

“…The specific conductivity, κ, of DMA was 2 × 10 −7 S•cm −1 at 298.15 K, which is in good agreement with available data. 12,13 Conductance measurements were carried out in a threeelectrode cell with the use of a Precision Component Analyzer 6430B (Wayne-Kerr, UK) under argon atmosphere and at the different frequencies, ν, (0.2, 0.5, 1, 1.5, 2, 3, 5, 10, 20) kHz. The temperature was controlled within 0.003 K (Calibration Thermostat Ultra UB 20F with Through-flow cooler DLK 25, Lauda, Germany).…”

The Standard Potential of the Silver-Silver Chloride Electrode in N-N Dimethylacetamide at 25°C

“…DMA (C. Erba reagent grade) was purified by fractional distillation under reduced pressure (2 mm Hg). The final product had a specific conductance of 4 x 10 -7 ohm -1 in good agreement with the value given in the literature (11).…”

Raman, infrared, and ultrasonic relaxation studies of some sodium and lithium salts in dimethylacetamide

“…It must be noted that failure to see a doublet in this spectral region does not exclude ion pairs in the NaN03-/DMA solutions and ultrasonic data, discussed below, reveal their existence. The conductance data of Sears et al 23 have also been analyzed with the inclusion of terms which allow for ionic association.…”

“…An attempt has been made to isolate the value of k¡ for NaN03 in DMA. Sears et al 23 have measured the electrical conductance of NaN03 in DMA at 25 °C over the concentration range (1.4-47.7) X 10~4 M. The data were analyzed by the Shedlovsky-Fuoss method28 and values for the limiting conductance, A0 = 71.53 ™1 cm"2 equiv™1, and the association constant, Kk = 50 M~\ were obtained. We have used the value for Kk (defined as (1 -a)/o2cay±2) and…”
