CIVL 175 Activity 7b
1. What is happening, in a microbial sense, during the fermentation? (There are two main
processes/reactions happening here: ethanol production and methanol production.
Extra Credit will be awarded for those that research and describe the methanol
production in addition to the ethanol process.)
Simple Distillation
1. What was the density of your distillate? How does your density compare to that of
water?
2. What does this tell you about the distillate and its components?
Fractional Distillation
1. What is the difference between simple and fractional distillation?
2. What was the density of your distillate? How does your density compare to that of
water?
3. What does this tell you about the distillate and its components?
