Abstract
Various methods used in the analysis of the activity coefficients for binary mixtures of symmetrical electrolytes are compared. The accuracies of these methods are examined through their standard deviations of the log γ fittings, maximun deviations max Δ, and the number of fitted points n, which have exceeded the experimental tolerance. The reason for the different degree of accuracy obtained are discussed in terms of the complexity of the g0 function.
