Transcribed Image Text:The following questionnaire must be completed and handed in to your teaching
assistant before starting the experiment.
1. Using the diagram in Figure 3, predict the following for the distillation of a
solution of x and y which has an initial concentration of 70% x and 30% y.
a. Initial boiling point
b. Vapor composition at initial boiling point
2. Suppose that gas chromatographic analysis of a solution of A and B gave peaks
with the following measurements: A, height - 180 mm, width at half-height- 4
mm; B, height - 64 mm, width at half-height- 7 mm. What is the composition
(weight %) of the solution?
Weight % A
Weight % B
3. Why are boiling stones added to the liquid to be distilled?
4. What error might occur if the thermometer in the distillation head was positioned
so that the mercury bulb was above the sidearm instead of in the correct position
