Question

A separating funnel is used to separate a mixture of water and mercury.

• A. True
• B. False

Answer 1

The correct option is A True

A separating funnel is used to separate a mixture of Water $\left({\mathrm{H}}_2\mathrm{O}\right)$ and Mercury $\left(\mathrm{Hg}\right)$.

• This is because mercury and water are immiscible with each other and mercury is denser than water due to which they form separate layers which can be separated with the help of separating funnel.

Separating funnel: It is an apparatus in which two immiscible liquids can be separated with the help of a stopcock fitted on the stem of the funnel.

Principle involved in the separation of mixture:

• Two immiscible liquids have different densities due to which they are present in the form of two different layers which can be separated by separating funnel.
• Immiscible liquids: When two or more liquids do not mix with each other, they are said to be immiscible. Example: vegetable oil in water.

Hence, the given statement is true.
