Method: set the equipment up like the diagram and then afterwards: 1. Pour the mixture containing ethanol, water and the yeast extract into the round bottom flask and begin heating it up. ...read more.

Problems encountered Many problems were encountered during the setting up stages of this experiment, because some unrequited equipment were placed together with the required equipment, which meant we had to use a trial and error method of setting the experiment up, the way we positioned some of the equipment was also a little dodgy-but this was swiftly rectified. ...read more.

Conclusion

We had conquered this problem because in theory ethanol's boiling point is roughly 70oC, if the chemical boiled at around 80oC to 100oC, it would mean its impure ethanol and should contain a liquid with a boiling point of roughly 100oC-like water. We were also able to tell that it contained ethanol because it should smell like beer-an alcoholic beverage; which is what ethanol is...an alcohol. Distillation Distillation is a common way of separating two chemicals in liquid form. ...read more.
