1. During the set-up of a distillation or a boiling point apparatus, the position of the bulb of the thermometer is crucial. Why is it so important in order to obtain accurate results? 2. According to what you have learned, the composition of the liquid and the vapor during a distillation is not the same. How do they change along the process? 3. What is the major obstacle that fractional distillation overcomes? 4. Why is fractional distillation more "efficient" than simple distillation? 5. During boiling point determination the temperature of the vapors is being measured and not that of the liquid. Explain why What was the purpose of the "boiling chips" during simple distillation? How did Gas Chromatography help you determine the composition of each fraction obtained through fractional distillation? 6. 7. e web and Windows
