Chemistry laboratories play an essential role in the education of undergraduate Science, Technology, Engineering, and Mathematics (STEM) and non-STEM students. The extent of student learning in any educational environment depends largely on the effectiveness of the instructors. In chemistry laboratories at large universities, the instructors of…

This experiment uses a radioactive technique to determine the relative leaving abilities of chloride and iodide in nucleophilic substitution reactions. (DT)

Two experiments are described which illustrate preparative as well as mechanistic features of the reactions of halogens with alkanes and alkenes. (DT)

By concentrating radioactivity contained on luminous dials, a teacher can make a high reading source for classroom experiments on radiation. The preparation of the source and its uses are described. (DT)

Describes a method for direct calculation of energy levels by using elementary techniques. Describes the limitations of the approach but also claims that with a minimum amount of labor a student can get greater understanding of atomic physics problems. (PS)

Eight laboratory exercises are described which involve the protein properties of hemoglobin, and six experiments are outlined which involve hemoglobin as a metalloprotein. (DT)

The Advanced Chemistry Laboratory Program is a project designed to devise experiments to coordinate the use of instruments in the laboratory programs of physical chemistry, instrumental analysis, and inorganic chemistry at the advanced undergraduate level. It is intended that such experiments would incorporate an introduction to the instrument…

Discusses a non-traditional unstructured laboratory approach designed to acquaint students with analytical techniques through the identification of two unknowns, one as a single component and one in a mixture, and the reading for the course facilitated by a detailed report on nine syntheses recently reported in the literature.
