Although several aspects of acid-base chemistry have been treated in the science education literature, a number of issues concerning acid-base equilibria have received little attention. In this paper, the misconceptions of a sample of twelfth-grade Greek students on the subject of acid-base equilibria are explored. Students"™ misconceptions and difficulties in understanding and applying the relevant concepts were categorized into seven categories: (a) dissociation and ionization, (b) definition of BrΓΈnsted-Lowry acids and bases, (c) ionic equilibria, (d) acid-base neutralization, (e) pH, (f) buffer solutions, and (g) degree of ionization.
