Question

What is the significance of fractionating column in fractional distillation?

Answer 1

1. Fractional distillation: Fractional distillation is a distillation type that involves the separation of two or more miscible liquids.
2. The process involves repeated distillations and condensations and the mixture is usually separated into component parts.
3. The separation happens when the mixture is heated at a certain temperature where fractions of the mixture start to vaporize.

Significance:

• The upward travel of liquid vapors is obstructed by a fractionating column.
• As a result, the low boiling liquid absorbs the energy emitted by the high boiling liquid. it remains in the vapour form.
• The high boiling liquid condenses and falls back into the distillation flask as it releases energy. As a result, a fractionating column aids in the separation of mixed components.
