1. During recrystallization, an orange solution of a compound in hot alcohol was treated with activated carbon and then filtered through fluted paper. On cooling, the filtrate gave gray crystals, although the compound was reported to be colorless. Explain why the crystals were gray and describe steps that you would take to obtain a colorless product. 2. The solubility of acetanilide in hot water (5.5 g/100 ml at 100 o C) is not very great, and its solubility in cold water (0.53 g/ 100 ml at 0 o C) is significant. What would be the maximum theoretical percent recovery from the crystallization of 5.0 g of acetanilide from 100 ml water. (assuming the solution is chilled at 0 o C). 3. If your experiment yield of acetanilide is greater than 100%, how could this occur? 4. Describe how would you separate a mixture of acetanilide and sand. 5. Why is fluted paper usually used when doing hot filtration during recrystallization?
