Sažetak
Properties of solutions of ionic surfactants depends also on the nature of counterions. Association of counterions at micellar surface compensates electrostatic repulsion between charged heads, thus stabilizing the micellar phase. Above critical micellization concentration the conductivity of the surfactant solutions is due to presence of micelles but also due to charged micellar species. Conductivity data, together with measurements of the hydrodynamic size and aggregation number of micelles were analyzed on the basis of the Site Binding Model, so that equilibrium constant for association of counterions with charged surfactant heads was obtained.
