Question
Which of the following apparatus is not used in the process of simple distillation?
- Thermometer
- Distillation flask
- Condenser
- Water bath
Hint:
Simple distillation involves heating the liquid mixture to the boiling point and immediately condensing the resulting vapors.
The correct answer is: Water bath
Simple distillation involves heating the liquid mixture to the boiling point and immediately condensing the resulting vapors. This method is only effective for mixtures wherein the boiling points of the liquids are considerably different (a minimum difference of 25
C).
The equipment for simple distillation usually consists of a burner or a heating blanket, a round refractory glass flask with a ground glass mouth, to allow its coupling, condenser, and some glass beads (some use a wooden stick) to reduce the size of the bubbles formed.
Water bath is not used in the process of simple distillation.
