The two fluid phases are separated by a membrane which is permeable to the small ions and impermeable to macroions, therefore, they interchange small ions whereas macroions are restricted to the β-phase. The permeability condition is imposed by assuming (in both phases) a constant chemical ...

Equilibrium chemistry
Equilibrium chemistry is a concerned with systems in chemical equilibrium. The unifying principle is that the free energy of a system at equilibrium is the minimum possible, so that the slope of the free energy with respect to the reaction coordinate is zero. This principle, applied to mixtures at equilibrium provides a definition of an equilibrium constant. Applications include acid-base, host-guest, metal-complex, solubility, partition, chromatography and redox equilibria.
