In the textbook (1st ed. - 1986), written in accordance with the approved course program, outlines the basics of chemical thermodynamics, the doctrine of chemical equilibrium, the physical chemistry of electrolyte and non-electrolyte solutions, the doctrine of boundary potentials and electromotive forces, chemical kinetics and catalysis. A brief description of the methods of chromatography, extraction, rectification, use of ion-selective electrodes is given. Initial positions of thermodynamics of nonequilibrium processes are considered.
