Abstract

An open-ended laboratory practical has been developed that challenges students to evaluate when different purification techniques are appropriate. In contrast to most lab practicals, the overall grade includes an evaluation of spectral analysis as well as writing skills. However, a significant portion of the grade lies in successful execution of a purification technique. Most importantly, being able to decide upon the best approach to purification is a crucial component of the exercise.
