Abstract:
A comparison of Hittorf and cell transference numbers provides a means of testing the validity of
the Onsager reciprocal relation for electrochemical systems with transference. Cell transference
numbers of aqueous cadmium chloride solutions at 25°C have been determined at concentrations
from 0.1 to 6 mol kg'1. Hittorf transference numbers for the same system have also been deter
mined. There is good agreement between both sets of values. The ionic transport coefficients of
irreversible thermodynamics lij have been calculated for concentrations from 0.1 to 1.0 mol kg-1 and
in this region the Onsager reciprocal relation is shown to be valid to within about 1 %.
