Question

Before shaking the separatory funnel containing the soda, what do you need to ensure?

Answer 1

Before shaking the separatory funnel containing the soda, you need to ensure that the stopcock is closed.

Step-by-step explanation:

In preparative chemistry, before shaking the separatory funnel containing the soda, you need to ensure that the stopcock is closed. This will prevent any liquids from escaping during shaking. Once the stopcock is closed, you can shake the separatory funnel to bring the two immiscible liquids into intimate contact.

Answer 2

Ensure the stopcock of the separatory funnel is closed before shaking to prevent leakage and have a proper grip on the stopper to prevent pressure release.

Before shaking the separatory funnel containing the soda, you must ensure that the stopcock is closed. This is to prevent any of the solution from leaking out during the shaking process, which could result in the loss of material and could be a safety hazard.

Additionally, it is essential to have a proper grip on the stopper at the top of the funnel to avoid accidental release of the stopper due to pressure build-up inside the funnel, very similar to opening a shaken carbonated beverage recklessly.
