In the Laboratory
The Blue Bottle Reaction as a General Chemistry Experiment on Reaction Mechanisms
Steven C. Engerer and A. Gilbert Cook
Valparaiso University, Department of Chemistry, Valparaiso, IN 46383
Cover
November 1999
Vol. 76 No. 11
p. 1519
Abstract
A kinetics/reaction mechanism experiment using the classic blue bottle reaction is described. Using the scientific method (observe, question, hypothesize, experiment, repeat) students propose and test possible reaction mechanisms for the methylene blue-catalyzed oxidation of dextrose with its dramatic color change. Students are led to discover the three-step mechanism through a series of questions. An advanced version for honors lab courses is also suggested.
Supplement
The student version of this experiment and the instructor version with notes are available.
