This course provides an attractive introduction to chemistry for a group of students who would normally avoid traditional chemistry courses. Topics include color, pigments, metals, ceramics, glass, paints, plastics, fibers, and dyes. (BB)

The history and definition of pH is presented along with sample calculations. (BB)

Presented here are improvements in the original design of an introductory statistical thermodynamics experiment with the result that heat capacities of metals are routinely obtained within ten percent of literature values. (BB)

In this paper an experiment is described in which the equilibrium constants necessary for determining the composition and distribution of lead (II)-oxalate species may be measured by linear sweep voltammetry. (Author/BB)

The setup described here for recording chemical transient phenomena is intended to be simple and an instructive example of interfacing experiments that can be performed on any microcomputer possessing adequate memory and input-output facilities. (BB)

Presents a literature review of wastewater disinfection for 1978. This review covers areas such as: (1) mechanisms of inactivation of negative microorganisms by chlorine and ozone; and (2) the effects of various treatment on over-all water quality. A list of 61 references is also presented. (HM)

Presents an outline of the chemistry involved and the steps which are being taken to gain a better understanding of the stratosphere. Chemical composition of natural stratosphere and depletion of ozone in the stratosphere by man-made pollutants are covered. (HM)

Describes the effect of "plant growth regulators" on plants, such as controlling the flowering, fruit development, plant size, and increasing crop yields. Provides a list of plant growth regulators which includes their chemical, common, and trade names, as well as their different use(s). (GA)

Describes a portion of a chemistry-oriented science course, the toxicology of the metal thallium, in the context of literature and related sources. (GA)

The Analytical Division of the American Chemical Society (ACS) questions criteria established by the Committee on Professional Training of the same organization concerning the role of analytical chemistry in freshman level courses. (CP)

Describes the genesis, development, implementation, and evaluation of a graduate level kinetics course based on selected influential papers in chemical reaction engineering. (BB)

The amount of carbon dioxide in the atmosphere is increasing at a rate that could cause significant warming of the Earth's climate in the not too distant future. Oceanographers are studying the role of the ocean as a source of carbon dioxide and as a sink for the gas. (Author/BB)

A practical exercise is described that allows students to investigate a specific problem using a variety of biochemical techniques. The need for a thorough understanding of the theoretical principles underlying these processes is emphasized. A program of private study and assessment is suggested to enable the progress of students to be followed.…

A new scale is suggested, with the objective of simplifying relationships between the various scales and units used in spectroscopy. Although there are certain drawbacks to such a scale, it is hoped that the suggestion will stimulate discussion on the relevance of the many scales and units that are used. (Author/BB)

Discusses some issues related to the use of the International System of Units (SI) in teaching chemistry. (HM)
