Description de la ressource pédagogique

Description (résumé)

This video is part of a series of 19 videos for technical gestures in chemistry (with French subtitles). In this video, two filtration techniques are presented to you which differ in their assembly: gravity filtration, and vacuum filtration. Filtration is a physical separation between a solid and a liquid. This is the case during crystallization, or recrystallization, where it is necessary to isolate the product from its solvent. This is also the case when one wants to separate insoluble and unwanted particles or a desiccant such as sodium sulphate or magnesium sulphate.
