Question
In the vacuum distillation process, the boiling point of component of liquid which is to be distil out becomes:
- Increases
- Decreases
- First increases and then decreases
- There will be no change in the boiling point.
Hint:
Distillation performed under reduced pressure, which allows the purification of compounds not readily distilled at ambient pressures.
The correct answer is: Decreases
Vacuum distillation is distillation performed under reduced pressure, which allows the purification of compounds not readily distilled at ambient pressures or simply to save time or energy. This technique separates compounds based on differences in their boiling points. This technique is used when the boiling point of the desired compound is difficult to achieve or will cause the compound to decompose.
In the vacuum distillation process, the boiling point of component of liquid which is to be distil out becomes decreases.
