Re lechatelieritelization Â Â Â Â Â Â Â Â Â Â Â The principle of recrystallization is quite simple (refer to figure 6 on the next page).Â The unattackable to be purified is re turn in an prohibit solution and allowed to reprecipitate or recrystallize more slowly thus preventing the entrapment of impurities in the crystal lattice. Â Â Â Â Â Â Â Â Â Â Â Â The solubility of a solute in a dissolving agent is a function not only of the chemical social organisation of the deuce components, but also of the temperature.Â Do you remember that temperature is a barroom of a molecules kinetic competency?Â unremarkably the solubility of a solid in a molten increases with temperature, and, in some instances, the effect may be truly marked (Table below).Â This phenomenon is of great importance to the chemist because it is the bottom for the refinement of solids by recrystallization.
