Describes a laboratory experiment which introduces basic principles and experimental techniques of mass spectrometry for fourth year undergraduate (B.Sc.) students. Laboratory procedures, background information, and discussion of results are provided for the experiment in which the natural isotopic abundance of chlorine is determined. (Author/JN)

Describes an experiment using a high-speed preparative centrifuge and calculator to demonstrate effects of the frictional coefficient of a macromolecule on its rate of transport in a force field and to estimate molecular weight of the macromolecule using an empirical relationship. Background information, procedures, and discussion of results are…

Background information, laboratory procedures, and discussion of results are provided for experiments designed to familiarize students with the biochemistry of nicotinamide coenzymes and the chemistry involved in their reactions. In addition, students are exposed to ultraviolet (UV)-spectroscopy as a tool for investigating reaction mechanisms in…

Describes laboratory inspection forms developed by the New York section of the American Chemical Society and recommends that they be used by qualified college safety officers. Includes instructions on how to order full-size copies of the forms suitable for duplication. (SK)

Explanations and four examples are provided which illustrate four steps needed to locate an organic compound in the Beilstein Handbook. (SK)

Describes impact of micrographics; microcomputer simulations of scintillation spectrometry and chemical/enzyme kinetics experiments; various computer programs (formulas and equations and equilibrium demonstration and lunar data plotting, among others); multiplexing in instrument readout displays; microcomputer-controlled flash photolysis…

Discusses computer simulation which focus students' attention on logical steps involved in qualitative analyses. (SK)

Various chromatographic techniques are reviewed, including, among others, elution, liquid-liquid, column-partition, qualitative and quantitative, and plan partition chromatography. (SK)

Techniques and instructional strategies for individualizing a high school chemical program are reviewed. (SK)

Offers suggestions for teaching South American, Arab, and Oriental students, focusing on typical problems these students face such as differences in culture, educational system, North American language, idiom, tests and grading, and classroom discussion. (SK)

Describes a high school chemistry course for students going to vocational institutes, community colleges, or allied health areas. Includes course outline and rationale for the course. (SK)

Two demonstrations are described: (1) red cabbage and electrolysis of water to bring together acid/base and electrochemical concepts; and (2) a model to demonstrate acid/base conjugate pairs utilizing magnets. (SK)

Describes a project and experimental procedures, suitable for a final year organic chemistry course, in which students synthesize a variety of substituted phenanthrenes, chrysenes, and benzo phenanthrenes. (SK)

Describes a sequence of experiments developed at Texas A&M University for use in one-semester and two-semester (nonmajors) organic chemistry courses to teach a maximum number of separation and purification techniques such as distillations, recrystallization, liquid-liquid extraction, and chromatography. (SK)

A fast-flow discharge reactor has been used in an analytical chemistry demonstration of gas phase titration, in inorganic preparative chemistry, and in physical chemistry as a "practice" vacuum line, kinetic reactor, and spectroscopic source as well as an undergraduate research tool. (SK)
