This paper describes the ideas held by 11 to 14‐year‐old Spanish students about solutions and the process of dissolution. It was found that, in general, these ideas relate to students’ everyday experiences and that they are only marginally affected by the science instruction received by the students. In attempting to explain the phenomenon of one substance dissolving in another, students usually focus on the solute, whilst assuming a ‘passive’ role for the solvent.
