The explicit consideration of ion exchange leads to a framework for the quantitative dissection and analysis of the influence of charged micelles on reactions which involve exchangeable ionic species. These include the following:(1) the bindingof a reactive ion to the micelle in the presence or absence of salt andpresence or absence of buffer;(2) the first-order reaction of an ionic substrate in the micelle;(3) the second-order reaction of an ionic nucleophile with a neutral substrate solubilized in the micellar phase;(4) the effect of micelles on the dissociation of weak acids;(5) the second-order reaction of the corresponding conjugate base.
