Question
Why is a condenser used in distillation process?
Advertisements
Solution
In the process of distillation, a liquid is converted into its vapor and the vapor is then condensed back to liquid on cooling. The condenser has a jacket with two outlets through which water is circulated. Hence, to provide efficient cooling, a condenser is used.
