Alka-Seltzer Fizzing--Determination of Percent by Mass of NaHCO3 in Alka-Seltzer Tablets: An Undergraduate General Chemistry Experiment.
Chen, Yueh-Huey; Yaung, Jing-Fun
Journal of Chemical Education, v79 n7 p848-50 Jul 2002
Presents a general chemistry stoichiometry experiment using materials involved in everyday life. From this activity, students learn that a chemical reaction occurs when an Alka-Seltzer tablet is dropped into water. Students also practice plotting experimental data through the use of a graphing program. Interpretation of the graph helps them comprehend the role a limiting reactant plays in the stoichiometry of a chemical reaction. (Author/MM)
