... What is it, and how do we do it? The process of recrystallization is used to purify a solid compound. The theory behind it reasons that as crystal X begins growing in solution, molecules of X will fit the crystal lattice better than molecules of Y, and X will be added preferentially. Thus, crystals ...

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.
