Question

Help please Why must you remove the stopper from the top of the seperatory funnel before opening the stopcock to drain out the tower liquid layer While using the seperatory funnel to perform an extraction, you may not be sure if the organic layer is on the top or on the bottom. how can you quickly differentiate the organic layer from the aqueous layer? Drew a detailed flow diagram to show how you would seperate the components of a mixture containing a neutral substances, toulene, and an acid substance, 2-naphthoic acid. Model your answer after the flow diagram we created on the board in the laboratory

Explanation / Answer

Answer:

1). It allows the air to exert pressure on the liquids, so that the liquid which is present at the bottom will move out of funnel easily.

2). It is to be noted that most of organic liquids are less dense than water. So, organic layer will be the top layer in most of the cases.

3). Both Napthoic acid and Toulene can be separated by using separating funnel. Or even distillation can be used for this separation.

3).
