Reaction, Microscale: Potassium Dichromate with Silver Nitrate A crystal of potassium dichromate is carefully combined with a solution of silver nitrate under a microscope. The reaction takes some time, so it is shown in a series of seven sequential videos. To see the entire reaction you need to play all seven.
The Chemistry of Swimming Pool MaintenanceCarl 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. Salter, Carl; Langhus, David L. J. Chem. Educ.2007, 84, 1124.

The Ultrasonic Soda Fountain: A Dramatic Demonstration of Gas Solubility in Aqueous SolutionsJohn 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. Baur, John E.; Baur, Melinda B. J. Chem. Educ.2006, 83, 577.

Students' Understanding of Solution Chemistry ConceptsTacettin 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. Pinarbasi, Tacettin; Canpolat, Nurtaç . J. Chem. Educ.2003, 80, 1328.
