The preliminary principles of chemical thermodynamics have been introduced in current inorganic chemistry text books but have not been well applied to examples. In this paper, the Gibbs free energy change Δ_rG_m^ϴ is taken as the main line of the teaching content of chemical reaction process. It is used to deal with the precipitation-dissolution equilibrium, oxidation-reduction equilibrium, acid-base equilibrium and coordination equilibrium with ionic reaction characteristics. These enable students to understand “chemical equilibrium” from the perspective of thermodynamics, overcome the drawbacks of describing “chemical equilibrium” in terms of chemical reaction rate kinetics, and achieve the essential understanding of “chemical equilibrium” and its application in reaction systems with ionic reaction characteristics. Moreover, the teaching content of the inorganic chemical reaction principles is reconstructed according to the main line of chemical thermodynamics.
