The Determination on the Ionic Average Activity Coefficient of Sodium Chloride in the n-Butanol Aqueous Solution

摘要

The electromotive force of pure NaCl aqueous solution has been determined using the ion selective electrode at 25°C. The electrode constants have been regressed. When the organic solvent of n-butanol has been added to the sodium chloride aqueous solution, the determination on the average activity coefficients of it has not been reported. The ionic average activity coefficients of sodium chloride in the aqueous solution and in the aqueous solution with n-butanol have been determined using the ion selective electrode at 25°C.
