Description (résumé)

This video is part of a series of 19 videos for technical gestures in chemistry (with French subtitles). In this video, you will learn how to perform recrystallization. It is a method for purifying a solid crude product. Indeed, at the end of a chemical reaction you isolate a crude product containing impurities which must be separated. If this product is solid, you can therefore purify it by recrystallization.
