摘要
Electrolytic conductivity measurements for a number of 1:1 electrolytes, including potassium chloride, potassium nitrate, tetramethylammonium chloride, tetraethylammonium bromide, tetraethylammonium perchlorate, hydrochloric acid, perchloric acid, methanesulfonic acid, p-toluenesulfonic acid, and the potassium salts of methanesulfonic acid and p-toluenesulfonic acid, are reported in binary aqueous mixtures containing 20, 40, 60, and 80 mass % ethylene carbonate at 25 degreesC. The conductivity data were analyzed by the Fuoss conductance-concentration equation to calculate the limiting molar conductivity Lambda (o), association constant K-A, and cosphere diameter R. The limiting ionic conductivities of eight ions were calculated using the known values of potassium and perchlorate ions. Walden products of ions in different compositions of ethylene carbonate + water mixtures were examined with respect to solvent structural effects and ion-solvent interactions.
