    • The first term on the right hand side of eqn. (12) would correspond to the Debye-Hückel law of variation of activity coefficient. The Φ([T]) term corresponds to the so-called "excluded volume effects". This term corrects the approximation used in obtaining the Debye-Hückel equation: in deriving this equation all the ions in the solution, except the central one, are considered as point charges. This is a good approximation when one is dealing with dilute solutions of small ions. Otherwise, it is necessary to correct the Debye-Hückel equation because of the effects derived from this approximation. In fact, when the excluded volume effects are corrected by fitting the experimental data, as in this paper, other effects are also corrected such as those derived from changes in the dielectric constant of the medium caused by the supporting electrolytes (or micelles)
