A Simplified Model To Predict the Effect of Increasing Atmospheric CO2 on Carbonate Chemistry in the Ocean  Brian J. Bozlee, Maria Janebo, and Ginger Jahn
The chemistry of dissolved inorganic carbon in seawater is reviewed and used to predict the potential effect of rising levels of carbon dioxide in the atmosphere. It is found that calcium carbonate may become unsaturated in cold surface seawater by the year 2100, resulting in the destruction of calcifying organisms such as coral.

Photooxidation of Bilirubin to Biliverdin and Bilirubin Structure  A. F. McDonagh and D. A. Lightner
Two recent articles in this Journal dealt with bilirubin (BR), the yellow pigment of neonatal jaundice. While BR is a fascinating biomedically-relevant tool for teaching photochemistry and stereochemistry, both articles are minefields of misinformation whose main pedagogical use might be as examples of error.

Steel Wool and Oxygen: A Look at Kinetics  James Gordon and Katherine Chancey
An experimental method is described to study the kinetics of the reaction of the iron in steel wool with molecular oxygen. A calculator-based data collection system is used with an oxygen gas sensor to determine the order of the reaction with respect to oxygen. Using the graphical method, students determine that the reaction follows first-order kinetics with respect to oxygen.

Greenhouse Gases and Non-gray Behavior  J. C. Jones
Greenhouse gases feature in many courses in applied chemistry as well as in courses on environmental science, atmospheric chemistry, and so on. We hear a great deal about such matters from the media. A more classical topic which first-year chemistry students will learn about in the physical chemistry component of their program is the black body concept and the StefanBoltzmann law. Recently in teaching about greenhouse gases to MSc students I have thought of a link between the topical and classical matters that is pedagogically interesting and might be of value to others teaching in this subject area.

The Determination of the Percent of Oxygen in Air Using a Gas Pressure Sensor  James Gordon and Katherine Chancey
A new detection method is applied to a classic experiment in which gaseous atmospheric oxygen in a test tube is reacted with the iron in steel wool to produce rust. A gas pressure sensor interfaced to a calculator-based data collection system was used to measure the percent of oxygen in the air as the reaction proceeded. The results from the calculator-based experiment were compared to the results from a more traditional water-measurement experiment. The average percent of oxygen obtained using the calculator system was 19.4  0.4%.

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.

Chemiluminescent Oscillating Demonstrations: The Chemical Buoy, the Lighting Wave, and the Ghostly Cylinder  Hernán E. Prypsztejn
In this article, a chemiluminescent oscillating reaction is presented in which a chemiluminescent substance (luminol) interacts with a chemical oscillator producing an oscillating chemiluminescence. This demonstration has been successfully performed in basic chemistry courses to arouse interest and curiosity in students. This demonstration fascinates audiences and in courses for science majors it is an excellent way to introduce complex concepts such as far-from-equilibrium conditions, nonlinear dynamics and bifurcation, and chaos theories.

Using Organic Light-Emitting Electrochemical Thin-Film Devices To Teach Materials Science  Hannah Sevian, Sean Müller, Hartmut Rudmann, and Michael F. Rubner
Light-emitting thin films provide an excellent opportunity to learn about principles of electrochemistry, spectroscopy, microscopic structure of the solid state, basic circuits, and engineering design. There is currently strong interest in academic and industrial engineering research centering on developing organic light-emitting devices for applications in flat panel displays. In this educational module, designed for high school or introductory undergraduate courses, students learn how to make a ruthenium-based thin-film device. In the process, they learn about the solid-state electrochemistry at work in the film, as well as the electroluminescence that results when current passes through the device.

Water in the Atmosphere  Joel M. Kauffman
None of eight college-level general chemistry texts gave a mean value for water in the atmosphere, despite its being the third most prevalent constituent at about 1.5% by mass as vapor and about 2% if clouds and ice crystals are included. The importance of water as a greenhouse gas was omitted or marginalized by five of the eight texts. An infrared spectrum of humid air was determined to demonstrate that water vapor, because of its higher concentration, was more absorptive than carbon dioxide. The cooling effect of clouds, or other influences on the Earth's albedo, were not mentioned in most of the texts. These pervasive errors should be corrected in new or future editions of textbooks.

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.

The Persistence of the Candle-and-Cylinder Misconception  James P. Birk and Anton E. Lawson
There is a persistent misconception that when a lighted candle is supported in a container of water and a closed cylinder is lowered over the candle, the candle is extinguished after a time by complete consumption of the oxygen in the cylinder, with a volume change corresponding to the amount of oxygen in the air. This misconception has appeared in the literature periodically for many years. Here, we present a number of experiments that refute this misconception.

Photocatalytic Degradation of a Gaseous Organic Pollutant  Jimmy C. Yu and Linda Y. L. Chan
A simple and effective method to demonstrate the phenomenon of photocatalytic degradation of a gaseous organic pollutant was developed. Titanium dioxide (anatase) was used as the photocatalyst, and sunlight was found to be an effective light source for the activation of TiO2. The organic pollutant degrade in this demonstration was a common indoor air pollutant, dichloromethane.
