Abstract
The formula for the stoichiometric mean ionic molar activity coefficient of strong electrolytes in aqueous solution at 25°C arising from Mayer's theory is compared with published experimental data. The agreement is good for sodium chloride to a concentration of about 0.4 molar; calcium chloride to a concentration of about 0.07 molar; zinc sulfate to a concentration of about 0.01 molar; and lanthanum chloride to a concentration of about 0.017 molar. Tables facilitating the computations and practical methods for the determination of the parameter of closest interionic approach and of the activity coefficient are given.Keywords
