A Kool Reaction from the Fine Print  Susan A. S. Hershberger and Arlyne M. Sarquis
Students investigate the reduction of artificial food dyes by citric acid-promoted oxidation of a metal in the form of fine or coarse steel wool. The artificial red and yellow food dyes present in drink mixes contain azo linkages (nitrogennitrogen double bonds) that are readily reduced to colorless products under mild reducing conditions.

Laboratory Experiments on the Electrochemical Remediation of the Environment. Part 7: Microscale Production of Ozone  Jorge G. Ibanez, Rodrigo Mayen-Mondragon, M. T. Moran-Moran, Alejandro Alatorre-Ordaz, Bruce Mattson, and Scot Eskestrand
Ozone, a powerful oxidizing and disinfecting agent, is produced electrochemically in the undergraduate laboratory with simple equipment and under very mild conditions. Tests are given to characterize it, to observe its action in simulated environmental applications, and to measure its rate of production.

Mass Relationships in a Chemical Reaction: Incorporating Additional Graphing Exercises into the Introductory Chemistry Laboratory  Stephen DeMeo
The purpose of this article is to increase student involvement with graph construction specifically in the context of introductory laboratory activities that involve mass relationships between reacting substances and products. In this regard, five massmass plots derived from a synthesis of a binary compound from its elements are presented as well as a set of questions to focus learners on the significance of each plot. The benefit of providing learners with these types of graphing activities include the use of higher-order cognitive processes as well as the elucidation of fundamental chemical knowledge such as the law of the conservation of mass, the law of constant composition, limiting and excess reactants, and empirical formula.

Kinetics of Alcohol Dehydrogenase-Catalyzed Oxidation of Ethanol Followed by Visible Spectroscopy  Kestutis Bendinskas, Christopher DiJiacomo, Allison Krill, and Ed Vitz
A two-week biochemistry experiment was introduced in the second-semester general chemistry laboratory to study the oxidation of ethanol in vitro in the presence of the enzyme alcohol dehydrogenase (ADH). This reaction should pique student interest because the same reaction also occurs in human bodies when alcoholic drinks are consumed. Procedures were developed to follow the biochemical reaction by visible spectroscopy and to avoid specialized equipment. The effect of substrate concentration on the rate of this enzymatic reaction was investigated during the first week. The effects of temperature, pH, the specificity of the enzyme to several substrates, and the enzyme's inhibition by heavy metals were explored during the second week.

Procedure for Decomposing a Redox Reaction into Half-Reactions  Ilie Fishtik and Ladislav H. Berka
The principle of stoichiometric uniqueness provides a simple algorithm to check whether a simple redox reaction may be uniquely decomposed into half-reactions in a single way. For complex redox reactions the approach permits a complete enumeration of a finite and unique number of ways a redox reaction may be decomposed into half-reactions. Several examples are given.

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%.

A Methane Balloon Inflation Chamber  Curtis J. Czerwinski and Tanya J. Cordes
While several lecture demonstrations are possible using methane-filled balloons, it is often inconvenient to prepare these balloons since the pressure from standard laboratory and lecture hall gas nozzles is too low. As a solution to this problem, a methane balloon inflation chamber, prepared from a translucent 3.5-gallon pail and an aspirator or house-vacuum, provides an inexpensive and convenient method for inflating balloons in laboratories or lecture halls. Prepared in this way, methane-filled balloons can be used to demonstrate the effects of vacuum, the lifting power of low-density gases, and the explosive combustion of methane.
