Question

What were some reasons why it was a good idea to remove the lid from the separatory funnel after each extraction? Select all that apply.

Answer 1

Liquid will no pour out. At the bottom the separating funnel consists of a valve it allow the liquid to flow out.The lid is on the top to pour in liquid from the top,it is air tight. Therefore as long as the lid is put, the liquid will not flow out at the bottom. The reason is that ,the incoming air has no way to get into the flask.
