ACTIVITY COEFFICIENTS OF MULTICOMPONENT STRONG ELECTROLYTES

This chapter considers five methods for calculating activity coefficients in multicomponent strong electrolyte mixtures. Generally, these methods are built upon the calculation of activity coefficients of single salt electrolyte solutions together with the application of certain mixing rules . The methods considered in this chapter are  

Pitzer - an equation using three to four parameters per ion pair, one 

Chen - a method using two parameters per water-salt pair and two parameters 

Application - A presentation of the specific predictive equations for activity coefficients which result from each of the five methods presented. 

Examples - A series of computer calculated runs and resultant comparative plots for specific multicomponent systems. Systems considered include
