Notes:
The activity of silver ion was measured potentiometrically with various sample solutions of silver or silver-sodium salt, prepared from three different kinds of carboxymethylcellulose, for the purpose of elucidating these several points: dependence of the activity coefficient of counter ion upon the concentration of polyelectrolyte in salt-free solutions; influence of the silver content of the sample upon activity coefficient; salt effect on activity coefficient; and dependence of activity coefficient upon the degree of neutralization. These experimental results indicate that the characteristics of polyelectrolyte solutions are in many respects quite different from those of simple electrolyte solutions. The applicability of the theory proposed by Ōsawa, Imai, and Kagawa is discussed in some detail, although the discussion is restricted to the salt-free system only.
