Santos, Elvira Santos; Gavilan Garcia, Irma Cruz; Lejarazo Gomez, Eva Florencia – Journal of Chemical Education, 2004
A comprehensive program in the field of green chemistry, which concentrates on processing and managing of wastes produced during laboratory experiments, is presented. The primary aim of the program is to instill a sense of responsibility and a concern for the environment through organic chemistry education.

Green, William J.; Elliott, Curtis; Cummins, R. Hays – Journal of Chemical Education, 2004
The importance of introducing various projects or activities as a motivation towards inquiry-based learning, also satisfies the need for first year chemistry students to transfer scientific theory into practice. This approach, combined with the traditionally written laboratory methods, develops creative skills, and the spirit of exploration…

Oliveira, Luiz C.A.; A. Rios, Rachel V.R.; Fabris, Jose D.; Lago, Rachel M.; Sapag, Karim – Journal of Chemical Education, 2004
An exciting laboratory environment is activated by the preparation and novel use of magnetic materials to decontaminate water through adsorption and magnetic removal of metals and organics. This uncomplicated technique is also adaptable to the possible application of adsorbents to numerous other environmental substances.

Marrs, Peter S. – Journal of Chemical Education, 2004
An exercise that provides a hands-on demonstration of the hydrolysis of aspirin is presented. The key to understanding the hydrolysis is recognizing that all six process may occur simultaneously and that the observed rate constant is the sum of the rate constants that one rate constant dominates the overall process.

Holman, John; Pilling, Gwen – Journal of Chemical Education, 2004
Chemical thermodynamics that is often considered abstract and demanding could be made more accessible by taking a contextualized approach. The trial of a course designed for chemistry majors dealing with gas laws and the first law of thermodynamics in the existing course are illustrated.

Hoffmann, Markus M. – Journal of Chemical Education, 2004
A classroom exercise that engages students as a team to develop an intuitive understanding of P-V-T phase behavior of a pure fluid is discussed. This exercise, when implemented in classrooms over a period of three years revealed that the students achieved a deeper level of understanding about phase behavior.

Myrick, M. L.; Colavita, P. E.; Greer, A. E.; Long, B.; Andreatta, D. – Journal of Chemical Education, 2004
The measurement of the infrared rotation-vibration spectrum of HCl(g) is a common experiment in the physical chemistry laboratory, which allows students the opportunity to explore quantization of rotational states in diatomic molecules. It is found that the CO2 vibration-rotation spectrum if used as an addition to the HCl experiment would give the…

Seen, Andrew J. – Journal of Chemical Education, 2004
An upper-level undergraduate experiment that, in addition to introducing students to catalysis using an air sensitive transition-metal complex, introduces the use of a solid acid as an activator and support for the catalyst is developed. The increased stability acquired in the course of the process affords the opportunity to characterize the…
