In the context of the thermodynamics of self-assembling systems, which predicts that both the number-average number of aggregation, N(n), of the ionic surfactants and the number-average degree of ionic dissociation of the micelles, alpha(n), depend on the concentrations of micellized surfactant and counterion in the bulk, it is shown that a key parameter is… (More)
