La neutralización ácido-base a debate

Abstract

The different meaning of neutralization depends of the context: Physics, Chemistry or Daily-Life context. Three definitions of neutralization were contemplated referring to the acid-base processes and it seems to be the origin of the alternative conceptions secondary school and university students have. The aim of this paper has been to identify the etymological, epistemological and educational aspects of acid-base neutralization to proposed teaching strategies to help students with their difficulties in this concept.
