Question
Which among the following component is separated by using the principle of steam distillation ?
- Glycerine from water
- Salt from water
- Bromobenzene
- All of these
Hint:
Steam distillation is a separation process that consists in distilling water together with other volatile and non-volatile components.
The correct answer is: Bromobenzene
Steam distillation is a separation process that consists in distilling water together with other volatile and non-volatile components. The steam from the boiling water carries the vapor of the volatiles to a condenser; both are cooled and return to the liquid or solid state, while the non-volatile residues remain behind in the boiling container.
Bromobenzene is volatile is separated by using the principle of steam distillation.
