Explanation / Answer

Ans 1. The stopper must be removed from the seperatory funnel before opening the stop cock because the draining liquid from a closed system may create a vaccum inside it the container. The air pressure pushes the liquid back in , countering the gravity . So as the container is opened , the stopper can shoot across the room or even worse the seperatory funnel may explode, due to the sjdden change in pressure. So it is always advisable to remove the stoppers first.
