This document is an instructional module package prepared in objective form for use by an instructor familiar with pH, measurement of pH with a pH meter and maintenance of pH meter electrodes. Included are objectives, instructor guides, student handouts and transparency masters. This module considers the definition of pH, types of electrodes and…

Provided is a study guide for an introductory minicourse to the principles of chemical reactions. This written text is designed to accompany a series of audio tapes and 35mm slides which the student studies at his own pace. The course presents chemical kinetics, reaction mechanisms, reaction rates, and equilibrium. (SL)

Suggests two uses for the programmable calculator in the freshman chemistry laboratory: as a means of determining whether or not a student's raw data from a laboratory experiment fall within acceptable tolerance limits; and as a means of checking the reliability of unknowns and grading on quantitative experiments. (MLH)

Describes a "feedback course" offered at Brown University, in which undergraduates redesigned the introductory organic chemistry laboratory. The students specified objectives for the ideal lab, then devised laboratory experiments. Laboratory safety was stressed, all dangerous reagents and solvents were eliminated, and toxicological data were…

Designed for first-year students of radiochemistry and atomic physics, this experiment tests the fundamental Moseley Law and introduces the method of elemental chemical analysis by X-ray fluorescence. (Author/MLH)

Provides abstracts and materials requirements for 20 chromatography projects. Experiments range in complexity; some require synthesis steps, apparatus construction, or special preparation techniques. (MLH)

Describes an experiment, for the general chemistry laboratory, intended to introduce the student to infrared spectroscopy. After being introduced to the theory of molecular vibrations on an elementary level, each student receives a list of 5-7 nickel (II) ammines to be prepared, analyzed and characterized by infrared spectoscopy. (MLH)

Discusses some of the most important structural features found in modern chemical laboratories, including building shapes, floor plans, and window utilization. (MLH)

Describes an experiment wherein the student can demonstrate the existence of all the thiocyanato chromium complexes, estimate the stepwise formation constants, demonstrate the robustness of chromium III complexes, and show the principles of paper electrophoresis. (GS)

Describes an experiment that will acquaint the student with the ion-exchange model, yield data which fit nicely to a computer type analysis, introduce the preparation of electrodes, provide a unique experience with elevated temperatures and ionic solvents, and provide experience in electrometric measurements. (GS)

Describes an experiment that illustrates the use of the preparative ultracentrifuge in isolating and purifying bacterial ribosomes, determines the sedimentation coefficients of the ribonucleoprotein particles, and demonstrates the subunit structure of the 70-S ribosome and the role of the magnesium ion in the association of subunits. (Author/GS)

Reports a modification of a simple method previously described for determining enthalpies of sublimation and comments on some of the method's inherent limitations. (Author/GS)

Lists the schools that are the big producers of chemistry graduates and lists the number of B.S., certified B.S., M.S., and Ph.D. degrees awarded by these schools in the 12 months ending June 30, 1974. Presents the full list of chemistry and chemical engineering graduates from all American Chemical Society approved departments. (GS)

Presents a description of the development of a laboratory-oriented chemistry course and the results noticed when the course was implemented. The syllabus was considered to be highly successful. (EB)
