Abstract

Various experimental methods may be employed for comparing the activities of solutions of electrolytes, viz., freezing point, boiling point, vapor pressure, osmotic pressure, electrical conductivity and electromotive force. Of these, the latter is generally more convenient of application; it has the advantage in that measurements are more easily made and its use is not restricted to any particular temperature interval. In solutions ranging from the moderately dilute to the very concentrated it may be applied more accurately than the conductivity method. The electromotive force method, however, has its limitations. It shares with all of the other methods the disadvantage of being inapplicable for solutions other than those of the uni-univalent electrolytes. This, coupled with the troublesome factor of the boundary potential, has limited its usefulness.
