Questions: Question 25 2 pts When neutralizing acids using a sodium bicarbonate extraction, why do you have to vent the separatory funnel immediately after inversion with the liquid mixture present inside? To remove impurities from the mixture To introduce oxygen and enhance extraction To prevent excessive pressure inside the seperatory funnel due to gas build up there is actually no need to vent

The question asks why it is necessary to vent the separatory funnel immediately after inversion when neutralizing acids using a sodium bicarbonate extraction.

Reason for venting

When sodium bicarbonate (\( \text{NaHCO}_3 \)) is used to neutralize acids, a chemical reaction occurs that produces carbon dioxide gas (\( \text{CO}_2 \)). This gas can build up pressure inside the closed separatory funnel.

Consequences of not venting

If the funnel is not vented, the pressure from the gas buildup can become excessive, potentially leading to the funnel's stopper being forced out or the glass breaking, which poses a safety hazard.

\(\boxed{\text{To prevent excessive pressure inside the separatory funnel due to gas build up}}\)

The answer is that venting the separatory funnel is necessary to prevent excessive pressure inside the funnel due to gas buildup from the reaction between sodium bicarbonate and acids.
