Abstract
The addition of alcohol (ethanol to hexanol) to micellar solutions of alkyltrimethylammonium bromides results in a decrease of cmc and of micelle molecular weight, and in an increase in the degree of ionization of micelles, at detergent concentration close to the cmc. Moreover the relaxation times for the exchange of detergent ions between micelles and surrounding solution and for the micelle formation-dissolution become much shorter (labilization of the micelles) upon addition of the alcohol. The degree of ionization of alkyltrimethylammonium bromide micelles in water-alcohol mixtures goes through a minimum when plotted as a function of the alkyl chain length. The various results have been interpreted in terms of the effect of solubilization of alcohol in the micelle palissade layer on the micelle surface charge density.

This can be simply demonstrated by deriving with respect to T the expression of the free energy of formation of an ion-pair. See for instance M. Emerson and F. Holtzer, J. Phys. Chem., 71, 3320 (1967).
