Presents a physical inorganic experiment in which large single crystals of the alkali halides doped with divalent ion impurities are prepared easily. Demonstrates the ion pairing of inorganic ions in solid solution. (CS)

Describes an experiment for general chemistry that illustrates the use of spectroscopy in the synthesis, characterization, and nitration of tris(acetylacetonato)cobalt (III). (CS)

Reassesses a common textbook misconception that "...phenols cannot be esterified directly." Results of experiments are discussed and data tables provided of an effective method for the direct preparation of phenyl acetate. (CS)

Describes events leading to a flood in the Wehr Chemistry Laboratory at Marquette University, discussing steps taken to minimize damage upon discovery. Analyzes the problem of flooding in the chemical laboratory and outlines seven steps of flood control: prevention; minimization; early detection; stopping the flood; evaluation; clean-up; and…

Reports results of a survey of college professors (N=146) on the present use of chemical instrumentation in undergraduate chemistry curricula of four-year colleges and universities in the United States. Uses in general, organic, analytical, physical, integrated, and research chemistry courses are noted. (JM)

Discusses the values presented in various handbooks for the boiling point and heat of vaporization of sulfuric acid, noting discrepencies. Analyzes various approaches to data presentation, discussing the data on sulfuric acid in light of the Trouton constant. Points out the need for a more critical use of tables. (JM)

Presents a largely experimental approach to the concept of mixed potentials, pointing out the close parallel that exists between equilibrium potentials. Describes several important examples of mixed potentials, providing current-voltage and polarization curves and half reactions as examples. Includes a discussion of corrosion reactions and…

Demonstrates how the symmetry properties of titration curves can be efficiently and rigorously treated by means of a simple method, assisted by the use of logarithmic diagrams. Discusses the symmetry properties of several typical titration curves, comparing the graphical approach and an explicit mathematical treatment. (Author/JM)

Defines "real world" examples providing rationale for incorporating them into chemistry teaching. Topic areas of papers include: chemistry in a watershed, polychlorinated biphenyl (PCB), consumer chemistry, culinary chemistry, using real world examples in a laboratory program, projects relating real world chemistry to high school students, and…

Describes industrial acetaldehyde synthesis/uses, explaining why acetaldehyde usage is declining in industry. Includes a discussion of the reaction chemistry, equations, and molecular structure diagrams. (JM)

Describes student involvement in conducting literature searches using the online literature retrieval methods of the Lockheed DIALOG system as a part of a junior-level Introduction to Independent Study Course. Outlines the teaching methods, presenting a set of practice questions with answers and discussing the progressive building of good study…

Provides an annotated list of 36 items for teaching the use of the chemical literature including price, address of suppliers, description and/or published evaluations whenever available. Materials include slides, audiocassettes, films, filmstrips, graphs, photographs, and videocassettes. (JM)

Reviews the present state of science curricula in light of the current crisis in science education, examining the problem of low science enrollment/achievement and its effect on society. Analyzes conflicting demands of preparing students for college and educating the large bulk of students who do not plan science-related careers. (JM)

Identifies assumptions and points out specific design questions which can help guide the development of successful programs to assist nontraditional students. Lists five myths identified as interfering with program development. Also reviews some factors to be considered in evaluating an assistance program and provides a concluding analysis. (JM)

Reviews software on: gas laws for IBM (disk available-SERAPHIM); gas chromatographic separation simulation for TRS-80 (listing available from author); vapor pressure data display with theoretical fit for Apple (author will copy on your disk); and second virial coefficients of nonpolar gases using the Kihara potential for TI-59 calculators.
