Question

What is the purpose of venting the separatory funnel?

1) To release pressure buildup
2) To prevent splashing
3) To allow for separation of immiscible liquids
4) To remove impurities

Answer 1

Venting a separatory funnel is crucial for releasing pressure buildup during liquid-liquid extraction, to ensure safety and prevent hazards.

Step-by-step explanation:

The purpose of venting the separatory funnel is to release pressure buildup that occurs when shaking the funnel during the process of liquid-liquid extraction. When two immiscible liquids are shaken together, they create an intimate contact that can cause gas or vapor pressure to build up within the funnel due to the solvents and the reaction between the solute and solvents. Venting allows this pressure to escape, preventing the risk of the separatory funnel potentially bursting or leading to hazardous splashing of chemicals. While the extraction process does allow for the separation of immiscible liquids and the removal of impurities, venting is specifically done to manage pressure for safety reasons.
