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
Math Skills
Acid Rain
Statistics
Acids and Bases
Kplot software
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.
Right click or control-click to download a zip file of the program:
Mac zip or
Mac dmg,
Windows 64 or
Windows 32,
Linux or
Raspberry Pi.
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.
Apporto (requires Beloit account) is the only option for chromebooks.
