A knowledge organiser on the A-level chemistry practical “preparation of aspirin" from 2-hydroxybenzoic acid and ethanoic anhydride using a phosphoric acid catalyst. The knowledge organiser includes the method and apparatus diagrams and goes into more depth about filtration under reduced pressure, recrystallisation and reflux. I use it in my lessons to go through the procedure in greater depth and then students refer to this when practising questions.
