Presents an outline of group separations for a nonhydrogen sulfide analytical scheme applicable to all metallic elements (Bromide scheme). Also presents another outline of an abbreviated and modified version (Iodide scheme) designed for emphasis on nutritionally important metals, with special attention to 10 cations. (JM)

Describes an undergraduate laboratory experiment used to illustrate the use of gas chromatography retention indices for the identification of unknown compounds, specifically for the identification of unknown compounds and for the identification of the volatile compounds responsible for the odor of the banana. Procedures, reference data, and sample…

Presents a new, recommended format for the periodic table which does not use the letters A and B to designate subgroups of elements. Also describes events leading to the adoption of this recommendation. (JM)

Discusses structure, phase transitions, and atomic volumes of the various period table families taking into account modern x-ray methods to the structure of the elements and to phase transformations as a function of temperature and pressure. Includes table and graph of atomic values at one atmosphere and room temperature. (JM)

This article brings together the principles of designing Likert attitude scales and demonstrates the procedure through the development of a chemistry attitude scale. Design procedures and validity and reliability of the scale are each discussed, with a data summary for the 20-item chemistry scale. (MNS)

A division of chemical education has been created within the chemistry department at Purdue University. The nature of chemical education, impediments to research and development in chemical education, and future directions of the division are discussed. (JN)

Provides tips to assist in preparing a training program designed to show that: (1) fire is dangerous; (2) ordinary individuals can neither understand fire nor extinguish it; and (3) a fire safety officer can do both. (JN)

Discusses an instructional strategy in which stoichiometric reactions are presented in terms of a recipe. Solutions for two different stoichiometric problems are included. (JN)

Suggests that academic departments reshape the intellectual climate for chemistry education as one way to ensure the future of chemistry. Current practices in chemistry and possible benefits which may result if the system is modified are examined. These benefits include better public support and understanding of chemistry. (JN)

Technological forecasters often fail to recognize the whole range of changing circumstances that may affect their predictions. Drawing on his own broad experience, the author offers basic reminders to those who set out to gauge the direction of future changes in technology. (IM)

Presents highlights of a symposium at which industry and academic personnel examined issues related to the training of analytical chemists. Recommendations to improve undergraduate and graduate curricula and comments on how to add content/topics to an already crowded curriculum are included. (JN)

Presents four generalizations about solubilities. These generalizations (rules), are useful in introducing the dynamic topics of solubility and in helping high school and introductory college chemistry students make some order out of the tremendous number of facts available. (JN)

Describes how to modify the commercially available and inexpensive Griffin-Worden (Kontes) glass pressure reactors to permit sampling of homogeneous reactions, without changing the relative concentration of species present. All required parts necessary for the modification are commercially available. (JN)

Procedures for recovering silver and cobalt from laboratory wastes (including those resulting from student experiments) are presented. The procedures are generally applicable since only common, inexpensive laboratory reagents are needed. (JN)

Background information, procedures used, and typical results obtained are provided for an experiment in which the stability constants of unstable complexes are determined. (JN)
