Abstract
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.

Thomas S. Kuntzleman and Christopher RichardsJournal of Chemical Education2010 87 (9), 993-993Previous letters and articles in this Journal have described methods for finding the pressure of CO2 inside carbonated beverages. One communication in particular describes a method for estimating this pressure without even opening the container. This ...

Laura B. Bruck and Aaron D. Bruck, Amy J. PhelpsJournal of Chemical Education2010 87 (1), 107-112Solubility is challenging for many general chemistry students, and the interactions of aqueous species are difficult to conceptualize. Derived from the pedagogies of Johnstone, Bloom, and Piaget, our primary research questions probe whether students’ ...
