Geosc 522- Geochemistry of Aqueous Systems

Instructor: S. L. Brantley
Texts:  Lectures will be derived from Stumm and Morgan, Principles of Aquatic Chemistry, and/or Morel and Hering, Principles and Applications of Aquatic Chemistry and/or Langmuir, Aqueous Environmental Geochemistry. Students should purchase one of these books. Also helpful, J.I. Drever, The Chemistry of Natural Water.
Credits: 3
Short Description: This course treats the basic thermodynamics and kinetics of aqueous systems from a fundamental standpoint. Topics include acid base chemistry, the carbonate system and alkalinity, dissolution and precipitation of minerals, and redox equilibria. Applications of the fundamental principles to groundwater, seawater, and hydrothermal fluids are examined.The course includes assigned problem sets as well as a paper and/or a presentation on a topic chosen by each student. Typically these projects incorporate the use of a geochemical equilibrium-solving code.
