Abstract
The Solvation Thermodynamics (ST) is a rigorous theory that describes the solvation as a well-defined process, and is based on the separation of the chemical potential into different terms with particular meanings. Although often mentioned, the interpretations of the nature of the terms within the so called “liberation energy” are rather stated than proved. Here we justify the meaning of the three parts of such energy, with relation to a particle in a fixed position and orientation inside a phase: the work required to give it freedom to move, to provide it energy for such translation (momentum) and to make it indistinguishable from particles of the same kind. The demonstrations reinforce the clarity of the solvation as a microscopic step by step process and the statistical mechanical basis of the ST, which supports the teaching of the subject in advanced courses.
