Question
The principle of separation of substances by using a separating funnel is based on:
- Different solubilities
- Same solubilities
- Same densities
- Different densities
Hint:
Separates two immiscible liquids.
The correct answer is: Different densities
A separatory funnel, also known as a separation funnel, separating funnel, or colloquially separating funnel, is a piece of laboratory glassware 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 lipophilic organic solvent.
Separatory funnels are used in the lab for liquid-liquid extractions, separating a mixture's components into two solvent phases of different densities.
