Abstract
A problem about solubility equilibrium is presented as a resource for the evaluation of students. It involves macroscopic, microscopic, and symbolic levels of representation, and allows one to assess whether students have acquired an adequate conceptual understanding of the phenomenon. The problem, which starts with a figure using numbered particles, is useful for judging the relationships that students establish among the three levels. The difficulties students encounter while solving the problem are discussed.
