Dissolution representations in Chemistry textbooks: the case of PNLEM. In Chemistry education, so as in other sciences, the use of images is fundamental in the process of teaching and learning. By virtue of this, the textbooks can be a vehicle of such importance, therefore contributing with many images and representations. In this context, the present work has as objective to promote the analysis of the six books approved by the “Programa Nacional do Livro do Ensino Médio, (PNLEM)”, being the main subject of investigation, the dissolution phenomena. Although the recognized importance of opperate in the theoretical and conceptual level to understand chemistry phenomena, our results suggest the need of greater reflection concerning the emphasis attributed to this hability. And so, this paper has as purpose contributing in the reflection of the professor during the choice and use of the LDs and in the process of evaluation of the same.
