As the title suggests, we introduce a novel differential approach to solution thermodynamics and use it for the study of aqueous solutions. We evaluate the quantities of higher order derivative than the normal thermodynamic functions. We allow these higher derivative data speak for themselves without resorting to any model system. We thus elucidate the molecular processes in solution, (referred to in this book "mixing scheme), to the depth equal to, if not deeper, than that gained by spectroscopic and other methods. We show that there are three composition regions in aqueous solutions of non-electrolytes, each of which has a qualitatively distinct mixing scheme. The boundary between the adjacent regions is associated with an anomaly in the third derivatives of G. The loci of the anomalies in the temperature-composition field form the line sometimes referred as "Koga line. We then take advantage of the anomaly of a third derivative quantity of 1-propanol in the ternary aqueous solution, 1-propanol – sample species – H2O. We use its induced change as a probe of the effect of a sample species on H2O. In this way, we clarified what a hydrophobe, or a hydrophile, and in turn, an amphiphile, does to H2O. We also apply the same methodology to ions that have been ranked by the Hofmeister series. We show that the kosmotropes (salting out, or stabilizing agents) are either hydrophobes or hydration centres, and that chaotropes (salting in, or destablizing agents) are hydrophiles.- A new differential approach to solution thermodynamics- A particularly clear elucidation of the mixing schemes in aqueous solutions- A clear understandings on the effects of hydrophobes, hydrophiles, and amphiphiles to H2O- A clear understandings on the effects of ions on H2O in relation to the Hofmeister effect- A new differential approach to studies in muti-component aqueous solutions

Solution Thermodynamics and its Application to Aqueous Solutions: A Differential Approach, Second Edition introduces a differential approach to solution thermodynamics, applying it to the study of aqueous solutions. This valuable approach reveals the molecular processes in solutions in greater depth than that gained by spectroscopic and other methods.

The book clarifies what a hydrophobe, or a hydrophile, and in turn, an amphiphile, does to H2O. By applying the same methodology to ions that have been ranked by the Hofmeister series, the author shows that the kosmotropes are either hydrophobes or hydration centers, and that chaotropes are hydrophiles. This unique approach and important updates make the new edition a must-have reference for those active in solution chemistry.

Unique differential approach to solution thermodynamics allows for experimental evaluation of the intermolecular interaction Incorporates research findings from over 40 articles published since the previous edition Numerical or graphical evaluation and direct experimental determination of third derivatives, enthalpic and volumetric AL-AL interactions and amphiphiles are new to this edition Features new chapters on spectroscopic study in aqueous solutions as well as environmentally friendly and hostile water aqueous solutions
