Zusammenfassung:A mathematical apparatus for describing the kinetics of chemical reactions accompanied by phase transitions is suggested. The phenomenon of stimulated precipitation is singled out. Together with spontaneous precipitation-solution, it allows periodic sedimentation (Liesegang rings) to be correctly described and the concept of solubility product to be corrected and generalized.
