Abstract
An experimental method is presented that leads to the development of solubility rules. A set of experiments is performed as a class demonstration and then discussed in groups. As a result, a classification of all the ionic species present can be made in terms of their solubility. This approach to the learning of solubility rules is significantly different from traditional methods in which students merely memorize rules. In the current method, student comprehension and involvement is increased.

“Gone” into Solution: Assessing the Effect of Hands-On Activity on Students’ Comprehension of Solubility
Laura B. Bruck and Aaron D. Bruck, Amy J. PhelpsJournal of Chemical Education2010 87 (1), 107-112“Gone” into Solution: Assessing the Effect of Hands-On Activity on Students’ Comprehension of Solubility
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’ ...
