Crystallization, Large Scale

This video shows the step-by-step process of purifying a solid through crystallization. A 4 gram sample of impure acetanilide (containing both soluble and insoluble impurities) is purified using water as solvent and a hotplate. Techniques include: boiling chips, boiling stick, oiling out, and scratching to initiate crystallization. Large scale suction filtration is shown in a subsequent video at:    • Suction Filtration, Large Scale   This video can be used with the free downloadable laboratory textbook found at: https://organiclabtechniques.weebly.com/
