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.

Let Us Give Lewis Acid–Base Theory the Priority It Deserves  Alan A. Shaffer
The Lewis concept is simple yet powerful in its scope, and can be used to help beginning students understand reaction mechanisms more fully. However, traditional approaches to acid-base reactions at the introductory level ignores Lewis acid-base theory completely, focusing instead on proton transfer described by the Br?nsted-Lowry concept.

Two "Gas-in-a-Bag" Reactions To Show the Predictive Power of the Relative AcidBase Strength Chart  Brett Criswell
Describes a demonstration in which two different pairs of solid chemicals mixed in two different Ziploc bags in the presence of a small quantities of water react to produce gases. Students are informed that the reactions are BrnstedLowry acidbase type reactions and must determine which member in each pair will act as the acid and which as the base.

Acid–Base Chemistry According to Robert Boyle: Chemical Reactions in Words as well as Symbols  David E. Goodney
Examples of acidbase reactions from Robert Boyle's The Sceptical Chemist are used to illustrate the rich information content of chemical equations. Boyle required lengthy passages of florid language to describe what can be done quite simply with a chemical equation.
