B. The stopper must be held in place while venting.
C.The stopper must be held in place while venting.
D.The separatory funnel must be inverted before venting.

Respuesta :

Answer:

Option B and C are not true

The statement is not true because the stopper has to be removed to release the pressure in the funnel to allow the liquid flow and if it is not removed, the vacuum formed above the liquid and bubbles would prevent proper draining or venting.
