Effect on observed temperature if thermometer bulb is placed below condenser should be determined. Concept introduction: Distillation is technique that is used to separate components of liquid mixture with help of selective boiling and condensation. This procedure either separates components partially or completely from mixture. It is one of physical process to separate mixtures and not by chemical reactions.

Students have asked these similar questions

1. The entire mercury bulb of the thermometer must be below the level of the side arm in order to obtain an accurate reading of the distillation temperature. Why is this so?2. Why is cold water circulated through the condenser from the bottom rather than from the top?4. In most distillations, the total volume of liquid obtained (distillate + residue) is not equal to the volume of the mixture introduced into the flask. What are the possible sources of loss in this procedure?

Use an apparatus similar to that shown and assume that the round-bottom flask holds 10 mL and that the Claisen head has an internal volume of about 2 mL in the vertical section. At the end of a distillation, vapor would fill this volume, but it could not be forced through the system. No liquid would remain in the distillation flask. Assuming this holdup volume of 12 mL, use the ideal gas law and assume a boiling point of 100°C (760 mm Hg) to calculate the number of microliters of liquid (d = 0.9 g/mL, MW = 200) that would recondense into the distillation flask on cooling.

The distillation flask is best completely filled with mixture as large as available never less than half empty about 70% full
