Abstract

In the chemistry curriculum of secondary education there are theories emerged historically in different contexts, such as acids and bases, which are progressively addressed throughout the curriculum. These cases could produce hybrid models, combining concepts from the different models which are presented, partly due to the ahistorical way in which are presented. This article analyses the conceptual difficulties more frequents in the Arrhenius and the Brönsted-Lowry models, and propose some teaching orientations that could help overcome the mentioned difficulties.
