Thus, after learning, we have proceeded by giving a paper and pencil task to students of two levels of teaching. The results obtained allow us to say that the assimilated knowledge is transitory; that the students have a worse perception of the base than of the acid concept and these two concepts are independent; that they associate the acid or base strength to its concentration; that the pH is far from being a "tool” of estimation of the degree of acidity; and that the students have difficulty in linking the empirical and the models' registers. Moreover, some alternative conceptions that can be harmful to the learning of Brønsted's model appear.
