Summary
The thermodynamic state of a saline solution is completely specified by the temperature, pressure and chemical potentials of the components that are present. The chemical potential can be defined rigorously in mathematical terms but in this form often provides difficulty in conception. In order to overcome this difficulty for solutions, it is useful to relate the chemical potential to some ideal reference solution; the deviation between real and ideal solution is formalized in terms of an activity coefficient, and sometimes in the case of a solvent by an osmotic coefficient. The activity coefficients can be obtained from experiment, and are well tabulated.
