THEORY OF ELECTRICAL CONDUCTANCE IN ACIDIC, AQUEOUS SOLUTIONS
Abstract
Protonic conduction occurs by the Grotthus mechanism. Below about 0. 00am HC1, the lengths of the Grotthuss chains are determined by the temperature, but over the range 0.001m to about 0.5m, the chains are principally disrupted by other protons, thus in this range the chain length and the equivalent conductance depend on the cube root of the concentration. An Arrhenius-type equation is developed for describing the concentration dependence of the conductance which yields values in agreement with experiment to within 1% over the range 5 to 65 C and up to 0.4m. The activation energy which appears in the chain-terminating terms of this equation is that of hole formation in the solvent water.
