Analysis of OxiClean: An Interesting Comparison of Percarbonate Stain Removers
Jeffrey D. Bracken and David Tietz

Vol. 82 No. 5

Abstract
Several different brands of oxygen-based multipurpose stain removers consist of simple mixtures of sodium percarbonate and sodium carbonate. A small sample of each brand of stain remover is decomposed and then analyzed. The observed difference in mass allows students to accurately determine the percentages of each component of the stain remover. A back-titration experiment and a precipitation reaction are performed to confirm the complete decomposition of the original mixture. This experiment provides an excellent example of how basic stoichiometry can be used to solve a real-world problem.
Supplement
A student handout is available.
