Question

Which of the following methods can be used for separating the components of a homogeneous solid-liquid mixture?

• A. Chromatography
• B. Separating funnel
• C. Distillation
• D. Sedimentation

Answer 1

The correct option is C

Distillation

Explanation for the correct option:

(C) Distillation:

• This method can be used for separating the components of a homogeneous solid-liquid mixture.
• It involves boiling the mixture to form vapours of the liquid and then cooling the vapours to regain the liquid. The solid particles remain in the container.
• For example, a mixture of salt and water can be separated by distillation.

Explanation for the incorrect options:

(A) Chromatography:

• It is a technique for separating the coloured components of a mixture, which have similar properties and dissolve in a particular solvent.
• Example: A mixture of coloured dyes can be separated by this method.

(B) Separating funnel:

• It is a glass apparatus for separating a mixture of two immiscible liquids.
• For example, a mixture of water and oil can be separated using a separating funnel.

(D) Sedimentation:

• It is a method of separating insoluble suspended solids from a liquid. On allowing the mixture to rest for some time, the heavier impurities settle down at the bottom and the clear liquid can be collected from the top.
• For example, a mixture of soil and water can be separated by this method.

Hence, the correct option is (C). Distillation can be used for separating the components of a homogeneous solid-liquid mixture.
