2. LEARNING OUTCOMES

Learning Outcomes

This course details the quantitative treatment of chemical processes in aquatic systems such as lakes, oceans, rivers, estuaries, groundwaters, and wastewaters. It includes a brief review of chemical thermodynamics that is followed by discussion of acid-base, precipitation-dissolution, coordination, and reduction-oxidation reactions. Emphasis is on equilibrium calculations as a tool for understanding the variables that govern the chemical composition of aquatic systems and the fate of inorganic pollutants.

Upon successful completion of this course the students will acquire new knowledge and specific skills on the following subjects:

  • To solve chemical thermodynamic equations and to determine the speciation of aqueous solutions of acids, bases, and minerals
  • To construct pH diagrams and titration curves, and solve the Proton Balance, Electroneutrality, and Mass Balance Equations for the speciation of solutions of acids, bases, and minerals
  • To determine the solubility of dissolved carbon dioxide, mineral salts, and metal oxides, hydroxides, and carbonates
  • Predict the behavior of environmentally important inorganic components under typical environmental conditions.
  • Apply knowledge of the behaviors of individual components in a system to explain real-world aquatic environmental systems.
  • Discuss how the presence of individual species, and their interactions, will affect the overall chemistry of a complex environmental system
