Exploration of SO[subscript 2] Scrubbers: An Environmental Chemistry Project
Schilling, Amber L.; Leber, Phyllis A.; Yoder, Claude H.
Journal of Chemical Education, v86 n2 p225-226 Feb 2009
The remediation of acid rain by SO[subscript 2] scrubbing is integrated into a laboratory project appropriate for first-year chemistry students. By burning a small amount of sulfur and bubbling the gas produced through distilled water, the student first observes one of the reactions that produces acid rain. The student then tests four different reagents (calcium carbonate, calcium sulfate, sodium carbonate, and potassium hydroxide) for their ability to neutralize SO[subscript 2](g), and then makes a conclusion about which could serve as potential SO[subscript 2] scrubbers for coal-burning industries. Their observations are rationalized with basic concepts such as pH, acid-base reactions, relative acidities, neutralization reactions, and solubility. (Contains 2 figures and 1 table.)
