Chapter 7, Problem 2Q

Interpretation Introduction

Interpretation:

Reason behind the removal of the stopper from a separatory funnel when liquid is being drained from it should be explained.

Concept introduction:

For daily laboratory liquid-liquid extraction, a separatory funnel is used. Two immiscible solvents can be readily separated by using the extraction technique.

Generally, one of the phases is organic, while the other is aqueous. The mixture of solvents that need to be extracted is poured from the top while stopcock at the bottom is still attached. Funnel is closed using a stopper,and two of the solvents are shaken together. Afterward funnel is inverted. The stopper is removed, and after the separation of layers, liquids are taken out in separate glassware.
