Unformatted text preview: 1. Boiling chips should be added 2. The round bottom flask should touch the hot plate at all time. 3. Do not heat too fast or too slow 4. Do not throw away the solution (reuse for both experiments then pour back to the bottle) 5. Work in pairs, only 2 students per one set up IV.Procedure: 1. Set the apparatus as in page 51 Mayo 2. Take 40 mL solution and boiling chips to round bottom flask 3. Heat it slowly (temperature knob at midpoint) 4. Get the temperature after every 2 mL collected 5. After 13 data points stop and switch to fractional distillation 6. Repeat steps 3 and 4 7. Plot a graph Hoang 2 V. Graph: The fractional distillation curve was steeper than the simple distillation curve. It is important in choosing which kind of distillation to use. VI. Conclusion: The experiment satisfied the purpose of the lab, which was to separate a misture of methanol and water. At the end of the experiment, methanol was separated from the mixture....
