Background information and procedures are provided for an experiment to prepare three metal derivatives of dimethyl sulfoxide (DMSO) and to determine some structural features of these derivatives based on their infrared spectra. Results and discussion of reactions involved are also provided. (JN)

Provides a prospective on electrosynthesis technology for chemical educators and students by discussing electrosynthesis reactions and experiments. Includes tables illustrating some electrochemical products, variables to consider in electrochemical reactions, indirect electrolysis of organic compounds, examples of direct/indirect electrochemical…

Eleven computer/calculator programs (most are available from authors) are described. Topics include visualizing molecular vibrations, dynamic nuclear magnetic resonance spectra of two-spin systems, programming utilities for Apple II Plus, gas chromatography simulation for TRS-80, infrared spectra analysis on a calculator, naming chemical…

Describes the construction of an apparatus which can be used to demonstrate vapor pressures of solids, liquids, and solutions. (SK)

Describes the relationship of Popper's theory of knowledge to chemistry instruction. Suggests that students be allowed to learn from their mistakes and presents five experiments with an implicit falsification purpose. (JN)

Presents the procedures involved in conducting a photochemical experiment intended to provide undergraduates with exposure to the synthetic advantages of organic photochemistry. (Author/SA)

Describes a laboratory demonstration in chemical equilibrium using ferric chloride and ammonium thiocyanate that would serve as a useful basis for an inquiry investigation. (BT)

Describes a programed, independent study, college level, general chemistry course designed to develop good technical laboratory skills with no attempt made to relate laboratory experiments and classroom topics. A list of experiments used and a sample laboratory examination are included. (BT)

Describes a high school chemistry experiment which involves the reaction between calcite and hydrochloric and sulfuric acids. This reaction can be carried out as a projected demonstration and on an individual basis. (HM)

A course is described that is designed to encourage exploration, conceptual invention, and expansion of an idea. Results are given that relate to curricular experimentation with chemistry. (SA)

Argues that many laboratory experiments are designed to be clever and challenging but instead are confusing and frustrating for most students. Describes the use of a teaching approach in English courses for chemistry laboratories in which students get to do the experiment for fun and practice, then meet with the teacher for discussion before…

Presented are the procedures and a discussion of the results for an experiment in which students select unknown carboxylic acids, determine their melting points, and investigate their solubility behavior in water and ethanol. A table of selected carboxylic acids is included. (CW)

Presents a laboratory experiment which illustrates the formation of tris(phenanthroline)cobalt complexes in the 2+ and 3+ oxidation states, the effect of coordination on reactions of the ligand, and the use of a ligand displacement reaction in recovering the transformed ligand. Uses IR, UV-VIS, conductivity, and NMR. (MVL)

Presents a short reaction sequence that allows the student to determine by spectroscopic methods the constitution and stereochemistry of the reaction products. Reports the interpretations needed to illustrate the usefulness of the spectroscopic method. Notes the products of the Michael-Aldol reaction have not been reported in the literature. (MVL)

Examines reading comprehension as it applies to the chemistry lab and describes techniques that promote better comprehension of lab materials. Lists four levels of reading to understand: literal, inferential, evaluative, and creative. Notes three methods to teach reading: the reference approach, mapping, and request. (MVL)
