Question

If dichloromethane (DCM) and water are used for differential extraction, then which of the following statements is correct? (A) DCM and water will form the upper and lower layers, respectively, in the separating funnel. (B) DCM and water will be completely miscible. (C) DCM and water will form the lower and upper layers, respectively, in the separating funnel. (D) DCM and water will form a colloidal mixture.

Dichloromethane (DCM) and water are immiscible liquids. Also, DCM has a higher density than water. So, when DCM and water are mixed together in a separating funnel, DCM will form the lower layer while water will form the upper layer.
