General Chemistry 3

In-depth study of acids and bases, chemical equilibrium, solubility, chemical thermodynamics, electrochemistry and the chemistry of the transition metals. The main chemical reactivities are studied: titrations, precipitations, oxidation-reduction and electrochemical reactions. Emphasis on chemical calculations (important formula, strategy and examples).
