Ion-selective electrodes were used to measure the activity coefficients at 298.2 K of individual ions in aqueous solutions of NaCl and NaBr up to of 5 molal and of KCl up to 4 molal. The mean ionic activity coefficients of NaCl, NaBr, and KC1, obtained from the values of the activity coefficients of
EMF measurements have been performed to study the influence of counterions in aqueous solutions of ionic surfactants in which the amphiphile is an n-alkyltrimethylammonium cation. General rules of variation were observed for the activities of the amphiphilic ion and the counterion, as a function of
