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.

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.

New Analytical Method for the Determination of Detergent Concentration in Water by Fabric Dyeing  Set Seng, Masakazu Kita, and Reiko Sugihara
This article describes a high school classroom activity in which an acrylic fabric is used as the extraction medium in the analysis of detergent concentration rather than more harmful organic solvents. An handmade reflection photometer, assembled with inexpensive materials such as LED, PVC tube, and CdS sensor, is used to determine the detergent concentration.

Linking Laboratory Experiences to the Real World: The Extraction of Octylphenoxyacetic Acid from Water  Jorge E. Loyo-Rosales, Alba Torrents, Georgina C. Rosales-Rivera, and Clifford P. Rice
A known quantity of the sodium salt of octylphenoxyacetic acid is dissolved in water, transformed to the acid (insoluble) form, and extracted using dichloromethane. These changes can be followed visually owing to conspicuous changes in solution turbidity.

Sedimentation Time Measurements of Soil Particles by Light Scattering and Determination of Chromium, Lead, and Iron in Soil Samples via ICP  Patricia Metthe Todebush and Franz M. Geiger
In this two-part general chemistry laboratory activity, students study soil samples from home and from campus. In part one, the samples are placed in water and the suspended colloid fraction is separated using filtration, followed by a determination of colloid sedimentation rates via light scattering. In part two, the solid phase of the soil samples is dissolved in acid and analyzed for chromium, lead, and iron using an inductively coupled plasma spectrometer. The experiment can be expanded to include arsenic. Through these experiments students can draw conclusions about the physical and chemical behavior of solid components in soil, paying particular attention to their propensity for transporting and chemically transforming pollutants in the environment.

Equilibrium Constants and Water Activity  David Keeports
General chemistry instructors are faced with a dilemma when introducing the topic of equilibrium constants: These constants are correctly written in terms of activities, yet activity is a complex topic better treated rigorously in a physical chemistry course than superficially in a general chemistry course. Thus, to introduce equilibrium calculations, it is necessary to use approximate forms for equilibrium constants. However, I find that some commonly used textbooks provide incorrect arguments leading to approximate equilibrium constants for aqueous reactions.

The Effect of Ionic Strength on the Solubility of an Electrolyte  Joan D. Willey
The theory of activity versus concentration is important in industrial, environmental, and biochemistry. The increase in solubility of an electrolyte in a solution of a second electrolyte with no common ions compared with pure water is not an easy concept to grasp because it seems to be counterintuitive. The simple experiment described here illustrates this principle visually and dramatically. Students attempt to dissolve CaSO42H2O (gypsum) in pure water and in 0.25 M NaCl.

Weak vs Strong Acids and Bases: The Football Analogy  Todd P. Silverstein
A football analogy for acids and bases in which acids are compared to quarterbacks, whose job is to get rid of the ball (H+). A strong acid, like an excellent quarterback, delivers the ball effectively; a weak acid, like a poor quarterback, is often left holding the ball. Furthermore, bases may be likened to wide receivers, whose job is to catch and hold onto the ball (H+).

Identifying Bottled Water: A Problem-Solving Exercise in Chemical Identification  Richard L. Myers
Students are challenged to identify water samples using the known chemical analyses of bottled waters. Several common water quality measurements such as hardness, alkalinity, and ion analysis can be used by students to identify the unknown water. This exercise develops problem-solving skills as students become familiar with basic lab techniques, quality control, data interpretation, and standard methods.

The Real Reason Why Oil and Water Don't Mix  Todd P. Silverstein
Authors should remove from their textbooks the incorrect enthalpic/hydrogen-bond explanation for the hydrophobic effect. Because aspects of the correct entropic/clathrate "cage" explanation lie beyond the scope of introductory or organic chemistry courses, it may be wisest to omit any detailed physical explanation of the "like dissolves like" phenomenon.

Complexometric Titrations: Competition of Complexing Agents in the Determination of Water Hardness with EDTA  M. Cecilia Yappert and Donald B. DuPre
The competition of complexing agents for the same metal ion and the formation of colored metal-ion complexes is demonstrated with the use of an overhead projector. This demonstration can be used to emphasize both the relevance of the relative values of formation constants in the complexation of metal cations and the applicability of complexometric titrations in quantitative chemical analysis.
