Annotation -
This lecture deals with basic aspects of analytical important chemical reactions in solution of solvents. This is made from point of view of equilibria and reaction rate of them. Reaction in solution of solvents: properties of solvents, dissolution of substances, the solvatation, ionic assotiation. Equilibrium constants, activity coefficient. Protolytic eqilibria in amphiprotic and aprotic solvents.
