What is Phenomenological Approaches in the Thermodynamics of Mixed Micelles with Electric Charges about?
## Hydrogen ion titration Counterion binding The stability of mixed micelles in general has been extensively studied by the molecular thermodynamic approaches as well as by the phenomenological or thermodynamic approaches. In this article, phenomenological approaches in the thermodynamics of charged mixed micelles, mostly on ionic/nonionic mixed micelles, are reviewed. The electrostatic interaction constitutes a main contribution to the excess free energy per monomer (in kT unit) g ex in the case of ionic/nonionic mixed micelles and the corresponding contribution is generally negative, known as the electric synergism. The origin of the electric synergism is shown to reside in positive curvatures of g ex,el (the electric part of g ex ) when plotted against the mole fraction of the ionic species x. Two types of the micellar Gibbs-Duhem (MGD) relations with (type 1) or without (type 2) the contribution from counterions are discussed to clarify various confusions found in the literature. Effects of varying ionic strengths with the micelle composition in the case of charged mixed micelles without any supporting electrolyte are discussed and a relevant way to correct for the effects is p
