Soil Equilibria: What Happens to Acid Rain?

This module, for use in an analytical chemistry course, considers the consequences when soil equilibria are stressed through the addition of combustion-generated sulfur and nitrogen oxides to the environment.

Students consider the chemical species important in the soil system charge balance; how changes in pH, solubility, and ion exchange affect ion distributions and concentrations; and how both chemical systems and ecosystems respond. Instead of many simple problems where individual equilibria are studied separately, students question and investigate facets of a more complex problem through laboratory measurements of model and natural systems, supplemented by case studies.
