Effects of water on proton migration in alcoholic solvents. Part 5.—Conductance of hydrogen chloride in methanol at 15, 25 and 35°C and in ethanol and pentan-1-ol at 15 and 35°C

Abstract

Conductance data are reported for hydrogen chloride in water + methanol mixtures at 15, 25 and 35°C and in water + ethanol and in water + pentan-1-ol mixtures at 15 and 35°C. Measurements were carried out in alcohol-rich mixtures over a water composition range up to about 20 % by weight. The results have been anlysed in terms of the Fuoss–Onsager conductance theory. The temperature dependence of the limiting molar conductance/viscosity product for hydrochloric acid in anhydrous methanol, ethanol and pentan-1-ol, respectively, is considered and discussed with respect to the influence of molecular solvent structure on the proton transfer mechanism.
