Geographical Information Systems (GIS) Mapping of Environmental Samples across College Campuses Kathleen L. Purvis-Roberts, Harriet P. Moeur, and Andrew Zanella In this laboratory experiment, students take environmental samples (concentrations of nitrogen dioxide) and geospatial coordinates with a global position systems unit at various locations around campus, map their data on a geo-referenced map with geographical information systems software, and compare their results to those observed by governmental agencies.

Fractional Distillation of Air and Other Demonstrations with Condensed Gases Maria Oliver-Hoyo and William L. Switzer, III This demonstration builds upon the commonly performed liquefaction of air not only to show the presence of nitrogen and oxygen, but also the presence of two other components, carbon dioxide and water. Several extensions are suggested: one to show boiling point elevation in solution and another to show the elevation of both boiling point and sublimation point with pressure. No special apparatus is required permitting presentations to audiences in a variety of settings. These demonstrations give the opportunity to discuss properties of gases, solution chemistry, and phase equilibria. Oliver-Hoyo, Maria; Switzer, William L., III. J. Chem. Educ. 2005, 82, 251.

Mass Spectrometry for the Masses Jared D. Persinger, Geoffrey C. Hoops, and Michael J. Samide In this article, we describe an experiment for an introductory chemistry course that incorporates the use of mass spectrometry for sample analysis. Several different air samples are collected that represent various chemical processes, and the composition of the air sample is predicted on the basis of known chemical principles. A gas chromatograph-mass spectrometer is used to analyze these samples, and the relative quantities of nitrogen, oxygen, carbon dioxide, water, and argon are calculated. On the basis of the data, the hypothesized sample composition is validated. Persinger, Jared D.; Hoops, Geoffrey C.; Samide, Michael J. J. Chem. Educ. 2004, 81, 1169.

A Novel Experiment for Fast and Simple Determination of the Oxygen Content in the Air Metodija Najdoski and Vladimir M. Petrusevski The reaction between nitric oxide (NO) and oxygen is used for determination of the oxygen content in the air. The nitrogen dioxide thus produced is dissolved in water. The volume decrease of the gas enables quick and accurate enough determination of the O2 content. The results of 20 measurements give %O2 = 21.04 0.63. Najdoski, Metodija; Petrusevski, Vladimir M. J.
