Chemical equilibria are fundamental in the understanding of biological and
environmental processes and in chemical analysis. This course emphasizes quantitative
and graphical interpretation of acid-base, solubility, distribution, complex
ion, and redox equilibria in aqueous solution and soils. Laboratory work stresses
application of gravimetric, volumetric, spectrophotometric, and potentiometric
techniques. Pre-professional preparation requiring one term of quantitative
analysis is satisfied by Chemistry 220. Three class periods and one laboratory
period per week. Offered each spring.
Prerequisites: Algebra; Chemistry 117 or facility with mole calculations.
Techniques and Prelab Material
Chemical Calculations and Review
Acids and Bases
Draw logarithmic concentration, distribution, and titration plots for acid/base, solubility, metal/ligand and redox equilibria, as well as cyclic voltammograms, Frost and Pourbaix diagrams.

You will need a way to unzip the file. You can place the resulting file/folder anywhere.
For Windows, the Kplot program will be inside the Kplot folder.
Since the Mac OSX application is not signed, you will need to control-click the app icon and choose Open from the context menu the first time you run it.
