Why and How To Teach Acid-Base Reactions without Equilibrium
Terry S. Carlton
Department of Chemistry, Oberlin College, Oberlin, OH 44074
Cover
August 1997
Vol. 74 No. 8
p. 939
Abstract
A stepwise method enables students to predict which acid-base reactions occur when two solutions are mixed. The complexities of equilibrium are avoided by treating reactions as all-or-none and by providing a table of acids in order of strength. Key steps, in order, are: list major species; classify them as acids and bases; identify the strongest acid and base; decide whether these two can react. If they do react, repeat these steps with the species that remain after reaction. Qualitative and quantitative examples are provided, as are simple rules for recognizing acids and bases from formulas. Advantages of the method and ways of adapting it to other types of reactions are described.

Chemistry Teacher Connection

The "Chemistry Teacher Connection" (CTC) is especially for high school chemistry teachers. For only $40/year, it offers an online-only subscription to CLIC along with membership in the Division of Chemical Education, normally $65/year. CTC subscribers receive access to all articles and supplements from 1996 through the current issue.
