In the Classroom
An Ionic Compound Logic Puzzle
Craig P. McClure
Department of Chemistry, University of Alabama at Birmingham, Birmingham, AL 35294
Cover
October 2009
Vol. 86 No. 10
p. 1210
Abstract
A logic puzzle is presented that has been developed as a review of a number of concepts related to ionic compounds. A number of clue statements are given, which are used to match student names to unknown aqueous solutions in a fictional laboratory. Finding the solution to the puzzle requires an understanding of proper ion ratios in an empirical formula, calculation of molar mass, precipitate formation, and polyatomic ions in ionic compounds. The puzzle also promotes logical thinking skills in the application of these concepts. This activity is appropriate for general chemistry students of all levels after an introduction to precipitate formation.
