Resumo
Solvation processes remain a topic with many unanswered questions. This is applicable to pure solvents and even more so to solvent mixtures. The increase in complexity that results from multiple solvent components, makes the description of solvation processes in solvent mixtures a true challenge. In this chapter we will deal with solvation in solvent mixtures and with the closely related topic of preferential solvation. \\nThe text will be organized along the following lines: a brief introduction to solvation processes in pure solvents, followed by an extension of the topic to mixtures, and finally a thorough analysis of preferential solvation phenomena. Different preferential solvation models will be introduced and explained in detail starting with empirical models, such as Langhals’ and Dawber’s, followed by a special note on spectroscopic models, e.g., Nagy’s and Suppan’s models, and then focusing on the more recent thermodynamic models, including those of Marcus, Ben-Naim, Covington, Bagchi, Skwierczynski/Connors, Bosch/ Rosés and El-Seoud. Among other issues, including whenever possible a brief historical overview, the mathematical formulations and a critical evaluation of the most relevant pros and cons of each model will be presented. The chapter will end with the extension of the latter models from binary to ternary mixtures\\n
