Describes an improved experiment of the thermal dehydration of copper (II) sulfate pentahydrate. The improvements described here are control of the temperature environment and a quantitative study of the decomposition reaction to a thermally stable oxide. Data will suffice to show sequential gravimetric analysis. (Author/SA)

Three methods are given for the synthesis of N-4 substituted sulfonamides. An example elucidates the procedures involved in one of the methods. The example is intended as a model for students. (SA)

This experiment, in which students experiment on themselves, involves carrying out analytical methods for vitamin C using instrumental and "wet" techniques. (SA)

After a short historical background, sources of information on reactive chemical hazards are discussed, along with reasons why these sources are not being tapped, particularly in academic laboratories, and some underlying principles. (BB)

Higher education is preoccupied with specialization and focused on the future work, career, and occupational competence of the individual. However, basic humanistic skills and hard moral choices should be as much a part of the education of a professional or scholar as are the knowledge and techniques of the discipline itself.

This article is designed to inform chemical educators not engaged in this technology as to the nature and methods used in the technology, the reasons for scientific and social concern, and the attempts made to assuage concerns involving recombinant DNA research. (author/BB)

This paper describes the Inventory of Piaget's Developmental Tasks, summarizes the data on its reliability and validity, comments on its usefulness as a quick, paper-pencil test which introductory chemistry instructors might use for assessing cognitive development, and presents data showing how introductory chemistry students scored on it.…

Recommendations are made to ensure that academic laboratories are safe and meet safety standards, instruction and information in laboratory safety are widely available, and that students, teachers, and academic research chemists give high priority to safety and health in their laboratories. (author/BB)

This academic genealogical tree shows the academic lineage of all tenured faculty members of the University of Wisconsin from the first professor of chemistry on. (BB)

Six short papers are presented on analytical chemistry in an integrated laboratory sequence, analytical chemistry at a junior college, the sophomore level analytical laboratory, the analytical textbook situation, and graduate level analytical chemistry. (BB)

A guided/open-ended format for general chemistry laboratories is used at the University of Oklahoma. This format is much more reflective of the scientific enquiry processes than the traditional verification format, and it allows students to investigate chemistry at a level consistent with their level of intellectual development. (BB)

The calculation of concentrations in the case of many simultaneous equilibria can be reduced to a search for a local minimum of a function of n variables, in which n denotes the number of mass balances involved. The method is simple and time-saving, but requires the availability of a computer. (author/BB)

Discusses the development of the periodic table of the elements, in particular, the idea that the elements could be ordered according to atomic number. (BB)

Discussed is the history of German universities, which were models for graduate education in the United States in the ninteenth century, with emphasis on the career of Emil Fischer. (BB)

Four examples are given of spectra of organophosphorus compounds which show students how the effects of phosphorus are delt with in nmr spectroscopy. (BB)
