Organization of measurable thermodynamic quantities and their relevance to analytical chemistry

A short discussion is given of the fundamentals of thermodynamics and of how the large number of measurable thermodynamic quantities can be organized in a clear and self-consistent way. The suggested "Thermodynamic Family Tree" also undelines the recent introduction of third order derivatives of Gibbs free energy as measurable properties with a sufficient accuracy. Those state functions are so new that they dont have a name nor a symbol yet! Finally some thoughts are given of how one should relate the thermodynamics to a recent discussion of H. Malissa [3] concerning the philosophy of analytical chemistry. © 1985 Springer-Verlag.
