Abstract

This work shows the exploration of alternative conceptions, on both acid and base concepts, of 8th and 9th grade secondary students. The obtained results clearly establish the need of intervening the curriculum execution, using educational strategies that can improve the integrating of everyday knowledge with scientific knowledge about acid and base concepts. An isolation of these studied concepts regarding chemistry language, chemical reactivity and fundamental biological processes was observed.
