Mixtures of two miscible liquids with two different boiling points were separated. Thus, the range in the example is not 122 o , but is 110-122 o C. Distillation will be stopped when about 0. The distillation is to take place at a rate no faster than five drops per minute.
We performed a boiling point test on the mixture to determine the unknown composition of the liquid. This report presents the results from a true boiling point. The procedure for this part of the experiment will be described during the laboratory lecture. The spreadsheet shows that the volume in the reboiler should be changing at a much higher rate than the column actually performed.
