Sažetak
Transference numbers of sodium ion constituent were determined at 298.15 K from the potential difference measurements of the cell with liquid junction, at various sodium chloride molalities against fixed molality in aqueous mixtures of ethanol (containing 20 and 40 mass % ethanol) by using literature data for the activity coefficient. Molar conductivities of sodium chloride were determined in both mixtures and treated by the Lee-Wheaton equation to obtain their limiting value. Limiting transference number of the sodium ion, obtained by extrapolation to zero-molarity, serves to derive ionic conductivities.
