Science Lab Experiment: Alcohol Distillation
Demonstration: Alcohol Distillation
Object: To prepare alcohol from a mixture of alcohol, yeast, water, and sugar.
Materials: alcohol lamp, glass, two side-arm flasks, two rubber stoppers,
rubber tubing, cooling tray, two clamps and stands, boileezer
Diagram:
Method: The materials were set up as shown in the diagram. The mixture was heated
to the boiling point. The liquid coming from the glass tubing was collected
and tested.
Observations: As the solution heated, bubbles formed. A vapour was noticed in the flask
and clear drops were seen to form at the end of the tubing. These drops were
collected and found to smell and taste like alcohol.
Conclusions: The yellowish mixture containing many materials was allowed to boil.
As it did so, the alcohol turned to the gas stage. As this gas hit
the cool sides of the tubing and second side-arm flask, it turned to
the liquid alcohol. Thus, alcohol was separated from the solution.
