... In this section, we introduce two different ways of expressing the concentrations of solutions: molarity and m olality. Sometimes, solutions are referred to as “dilute” or “concentrated,” but these are not very definite terms. “Dilute” just means that there is a relatively small amount of solute i ...

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.
