Q2. Explain about batch distillation
Ans. 
Batch distillation is a process of separating components of a mixture based on their boiling points.
• It involves heating a mixture in a batch still and collecting the vapor as it condenses.

• The components with lower boiling points will vaporize first and can be collected separately.

• The process is repeated multiple times to achieve higher purity of the desired component.

• It is commonly used in the production of alcoholic b...read more
