The Chemistry of Swimming Pool Maintenance  Carl Salter and David L. Langhus
This paper examines the key ideas behind swimming pool chemistry -- the central importance of pH and its effect on chlorine sanitation and calcium carbonate solubility. The paper also reviews the analytical procedures and common practices used to monitor and control pool chemistry or correct problems.

The Ultrasonic Soda Fountain: A Dramatic Demonstration of Gas Solubility in Aqueous Solutions  John E. Baur and Melinda B. Baur
An ultrasonic bath is used to accelerate the rate at which carbonated beverages equilibrate with the atmosphere. The resulting fountain, which can reach heights in excess of 3 meters, is a dramatic demonstration of the solubility of gases in liquids.

Students' Understanding of Solution Chemistry Concepts  Tacettin Pinarbasi and Nurtaç Canpolat
This study examines undergraduates' understanding of some concepts in solution chemistry such as unsaturated, saturated, and supersaturated solutions; physical properties of solutions; and gas solubility. We suggest that the results can be utilized in research that develops teaching strategies to overcome students' misunderstanding.

Understanding Solubility through Excel Spreadsheets  Pamela Brown
This article describes assignments related to the solubility of inorganic salts that can be given in an introductory general chemistry course. These assignments address the need for math, graphing, and computer skills in the chemical technology program by developing skill in the use of Microsoft Excel to prepare spreadsheets and graphs and to perform linear and nonlinear curve-fitting.

The Ammonia Smoke Fountain: An Interesting Thermodynamic Adventure  M. Dale Alexander
The ammonia smoke fountain demonstration utilizes a modification of the apparatus used in the standard ammonia fountain. The modification allows for the introduction of hydrogen chloride gas into a flask of ammonia rather than water. The flow rate of hydrogen chloride gas into the flask in the smoke fountain is not constant, but periodic; that is, the smoke puffs from the end of the tube. This unexpected behavior elicits an interesting thermodynamic explanation.
