Question

What will happen if the upper outlet of the condenser is connected to the tap instead of the lower outlet?

Answer 1

• If water enters through upper outlet of condenser, the water will quickly flow down under the influence of gravity. This allows only a small section of the condenser to be cooled enough.
• If water enters through lower outlet of condenser, the entire condenser will be filled with water before it leaves out providing maximum cooling to the condenser. This results in maximum recovery of purified liquid.

Hence,

Water must be allowed to enter through lower outlet of condenser during distillation process.
