Describes a method of flow injection analysis intended for calculation of complex-formation and redox reaction stoichiometries based on a closed-loop configuration. The technique is suitable for use in undergraduate laboratories. Information is provided for equipment, materials, procedures, and sample results. (JM)

Reports an experimental procedure for studying Einstein's theory of Brownian movement using commercially available latex microspheres and a video camera. Describes how students can monitor sphere motions and determine Avogadro's number. Uses a black and white video camera, microscope, and TV. (ML)

Explores the selection, source, funding, time constraints, and community support involved in developing carefully planned and executed science projects. Lists 21 kinetics experiments noting the instrumentation needed and the original references. (MVL)

Describes an experiment in which the rate of reaction can be followed using a colorimeter and data can be used to determine order of reaction, rate constant, and energy of activation. (GS)

Describes experiments used to illustrate the kinetics of reversible chemical reaction. (SL)

Describes an undergraduate physical chemistry experiment in which the acid catalyzed hydrolysis of sucrose is used to determine the catalytic coefficient of the hydronium ion, the catalyst in this reaction. (MLH)

Describes two experiments, one involving the electrolysis of potassium iodide and the other involving a diffusion process in solid copper. (GS)

Describes an open-ended experiment involving a bioinorganic system that provides the student a direct link between thermodynamics and kinetics. It utilizes a rapid reaction technique and requires one to clearly understand the relationship of experimental observable (absorbance) to a mechanism. (GS)

This experiment is designed specifically for students with little knowledge of radical reactions and provides an introduction to the gas-phase chemistry of radicals. Experimental planning based on the student's own observation is an important component of the experiment. (Author/MA)

Describes an experiment that generates data for calculating the ratio of molecular separation in a gas to molecular diameter. (GS)
