The Role of Water Chemistry in Marine Aquarium Design: A Model System for a General Chemistry Class Jeffrey J. Keaffaber, Ramiro Palma, and Kathryn R. Williams
Water chemistry is central to aquarium design, and it provides many potential applications for discussion in undergraduate chemistry and engineering courses. This article uses a hypothetical tank to house ocean sunfish as a model to show students the calculations and other considerations that are needed when designing a marine aquarium.

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.

Isolation of Copper from a 5–Cent Coin. An Example of Electrorefining Steven G. Sogo
The United States 5cent coin, commonly known as a "nickel", is made of an alloy containing 75% copper and 25% nickel. The experiment is a visually appealing illustration of the process of electrorefining using selective reduction.
