An experimental procedure is described for studying oxygen uptake by a transition metal. This procedure is designed for use with undergraduates and may be used in organic or biochemistry laboratories. Diagrams of the apparatus are included. (MR)

The experiment described here involves simultaneous monitoring of pH and NMR chemical shifts during an aqueous titration of alpha- and beta-alanine. This experiment is designed for use in an undergraduate biochemistry course. (MR)

Two experiments are described and appropriate discussion is given to illustrate the use of substoichiometry and saturation analysis techniques with undergraduates. The first experiment is the determination of silver content in photographic film. The second is the estimation of a hormone concentration using saturation analysis and a commercially…

Describes a chemical experiment which illustrates the Beckman rearrangement and ring opening reactions. (SL)

Describes an open-ended chemistry laboratory project for organic chemistry laboratories. (SL)

Discusses the biocidal/toxicological applications of organo derivatives of true metals. (SL)

Describes the role of eight different metal ions in the chemical functioning of the human body. (SL)

Utilizes a pretest-posttest design to determine if participants (N=26) exhibit significant gains in organic, inorganic, and biological chemistry concepts as the result of a six-week summer program. Significant gains in these areas and in an understanding of the methods and procedures used in scientific explanation are found. (CP)

Provides an outline for a semester course in the history of organic chemistry. (SL)

Included are demonstrations on optical activity, and using a digital multimeter. (SL)

Contains contributed suggestions for laboratory equipment, chemistry activities, and explanations of chemical reactions. (CP)

Describes a science activity designed for undergraduate biochemistry classes. Provides background, a list of materials, experimental procedures, and the results of this experiment. (CW)

Presents a practical exercise that enables students to measure flux control coefficients in a metabolic pathway in vitro, to verify the summation property, and to compare the differences in the distribution of these coefficients in different steady states. Discusses background, materials, methods, and results of the activity. (CW)

Discusses modifications in the fatty acid monolayer experiment to reduce the inaccurate moleculary data students usually obtain. Copies of the experimental procedure used and a Pascal computer program to work up the data are available from the authors. (JN)

Chemical reaction rates can be controlled by varying composition of miniscule clusters of metal atoms. These bimetallic catalysts have had major impact on petroleum refining, where work has involved heterogeneous catalysis (reacting molecules in a phase separate from catalyst.) Experimentation involving hydrocarbon reactions, catalytic…
