Question

A bottle containing two immiscible liquids is given to you. These may be separated by:

• A. fractionating column
• B. separating funnel
• C. fractional distillation
• D. steam distillation

Answer 1

The correct option is B separating funnel

Separating funnel is used in liquid-liquid extractions to separate (partition) the components of a mixture into two immiscible solvent phases of different densities.

Typically, one of the phases will be aqueous, and the other a non-polar lipophilic organic solvent.

Most organic solvents float on top of an aqueous phase, though important exceptions are most halogenated solvents.

Option B is correct.
