Crystallization, Small Scale

This video shows the step-by-step process of purifying a solid through crystallization. A 1 gram sample of impure NBS (N–bromosuccinimide) is purified using water as solvent and a hotplate. Techniques used include: boiling chips, boiling stick, paper towel holder, and scratching to initiate crystallization. Suction filtration is shown in a subsequent video at:    • Suction Filtration, Small Scale   This video can be used with the free downloadable laboratory textbook found at: https://organiclabtechniques.weebly.com/
