Distillation in the chemistry laboratory is an essential part of a practicing chemists' and a chemistry educators' work. Nevertheless, regardless of the degree of importance in each of the aforementioned professions, few educational studies on teaching and learning distillation exist. In an effort to rectify this oversight, the Department of Chemical Education at Utrecht University engaged first year chemistry majors in a qualitative study aimed at acquiring an understanding of the processes of conceptual development that do, or do not, take place when students are performing distillation experiments. The results include: (1) discussions of distillation from a chemical point of view; (2) detailed descriptions of the problems that occur when students are distilling during laboratory experiments; (3) an interpretations of the problems; and (4) ways to avoid problems with the help of different teaching strategies.
