Conductance of symmetrical, unsymmetrical and mixed electrolytes. Part 2.—Hydrodynamic terms and complete conductance equation

Abstract

In this series of papers, the derivation of a conductance equation based on a new model for ions in solution is described. The equation describes charge transport in solutions containing any number of ionic species, of any valency type. In the second paper of this series, the hydrodynamic velocity field about a given ion is examined, and expressions are obtained for the electrophoretic retarding velocity, and the hydrodynamic component of the relaxation field, acting on a given ion. The final conductance equation is assembled, and its application to the analysis of data for solutions containing mixed or associated unsymmetrical electrolytes is discussed. By reduction of the general equation, an expression is obtained for the “ special case” of a solution containing a single symmetrical electrolyte. The use of Physical and Chemical Models for electrolyte solutions is examined critically.
