ACTIVITY COEFFICIENTS OF SINGLE STRONG ELECTROLYTES

This chapter traces the history of activity coefficient models for aqueous solutions of single strong electrolytes. Of great importance is the Debye-Huckel equation, which has been the cornerstone of more recent models. In addition to Debye-Huckel, the following, more recent methods are outlined  

Guggenheim s equation - a one parameter equation with published parameter values for calculations at 0 and 25° C 

Davies equation - a suggested equation for the Guggenheim parameter 

Meissner s equation and plot - a one parameter equation for reduced activity coefficients and a generalized family of curves from which it is proposed graphical predictions can be made
