“…Regarding solvation equilibria, it has been described that solvation of cations and anions of chlorides in alcohol/watermixtures is preferentially by water, and only at very high alcohol concentrations (i.e., at very low water content) the fraction of alcoholically-solvated ions is increased; these chlorides would not be available for corrosion [68]. For small water content in ethanol/gasoline, the system is homogeneous and also the chlorides are homogeneously distributed in the bulk solution.…”

“…The basic concept of such an approach is that a particular reaction rate, equilibrium or spectral effect is suitable to serve as a model for other reactions 4. Several polarity scales2 exist, but the donor–acceptor approach developed by Gutmann5, 6 precedes all other polarity scales and plays a seminal role in solution chemistry 7, 8. In this approach, the donor number (DN) is a quantitative measure of Lewis basicity and the acceptor number (AN) a quantitative measure of Lewis acidity, respectively.…”

Solute properties are known to be strongly influenced by solvent molecules due to solvation. This is due to mutual interaction as both the properties of the solute and of the solvent strongly depend on each other. The present paper is based on the idea that ionic liquids are cations solvated by anions and anions solvated by cations. To show this (in this system strongly pronounced) interaction the long time established donor–acceptor concept for solvents and ions in solution by Viktor Gutmann is extended to ionic liquids. A number of solvent parameters, such as the Kamlet–Abboud–Taft and the Dimroth–Reichardt ET scale for ionic liquids neglect this mutual influence, which, however, seems to be in fact necessary to get a proper description of ionic liquid properties. It is shown how strong such parameters vary when the influence of the counter ion is taken into account. Furthermore, acceptor and donor numbers for ionic liquids are presented.

“…By the detachment of the parts from the latter, the characteristics of the parts within the whole are irretrievably lost, but they are indispensable for the functions within the superordinated system [4] When chemists became interested in quantitative relationships, they did not try to replace the search for qualities by that for quantities but rather to proceed jointly with qualitative and with quantitative studies. The establishment of the periodic table serves as an example for the success of these joint considerations [5]. Doebereiner had noted similarities in properties between certain elements and grouped them together in "triads" Mendeleev arranged the elements according to their quantitative characterization by increasing atomic weights and grouped them by making use of similarity considerations, as they are required in order to gain an understanding of qualities.…”
