Exploding Soap Bubbles: Hydrogen + Oxygen A series of three videos shows that as the ratio of oxygen to hydrogen in soap bubbles increases, the explosions that occur when the bubbles are ignited get louder. (The fact that with an excess of oxygen the explosions would become softer again is not shown.) Each video is repeated with no voice-over so that only the sounds of the explosions are heard. Five still images are provided to show the stoichiometry on the molecular scale. The videos are intended to be shown in order beginning with Hydrogen Alone and ending with hydrogen plus more oxygen.
Amino Acid Complementarity: A Biochemical Exemplar of Stoichiometry for General and Health Sciences ChemistryEd Vitz Calculations demonstrating amino acid complementarity are presented as an interesting application of stoichiometry. Food proteins are said to have complementary amino acids when the proteins combine to provide amino acids in the proper stoichiometric ratios to synthesize human protein. Implications for vegetarian diet, efficiency of food production, and diet adaptations in various cultures are explored briefly. Vitz, Ed. J. Chem. Educ.2005, 82, 1013.

Classroom Demonstration of a Spot Test for Phenylpyruvic Acid and Its Relationship to PhenylketonuriaChristopher J. Halkides A classroom demonstration of a spot test for phenylketonuria using ferric chloride is discussed. The chemistry is similar to that used in Phenistix test strips. Some background information on screening infants for phenylketonuria is also given. Halkides, Christopher J. J. Chem. Educ.2004, 81, 366.
