Question

Milk is an example of

• A. Emulsion
• B. Solution
• C. Gel
• D. Suspension

Answer 1

The correct option is A

Emulsion

Explanation for correct answer:

Option (A) Emulsion

• The mixture in which one substance of dispersed insoluble particles is suspended throughout the other substance is known as colloids.
• Colloids can be classified on the basis of the phase of the dispersed substance and the phase in which it is dispersed.
• Sol, emulsion, foam, and aerosol are the different types of colloids.
• The colloidal suspension with solid particles in a liquid is known as Sol.
• An emulsion is a mixture of two liquids.
• Foam is formed when many gas particles are trapped in a liquid or solid.
• Aerosol contains small particles of liquid or solid dispersed in a gas
• Milk is a colloid in which a liquid is dispersed in a liquid.
• An emulsion is a mixture of two or more liquids that are immiscible owing to liquid-liquid phase separation.
• In milk, the fat and water cannot be mixed together to form a solution thus two immiscible phases of liquids are visible.
• Hence option (A) is correct.

Explanation for incorrect answer:

Option (B) Solution

• A solution is a homogeneous mixture of two or more substances.
• In milk, the fat and water cannot be mixed together to form a solution thus two immiscible phases of liquids are visible.
• Therefore, it is an example of an emulsion
• Hence option (B) is correct.

Option (C) Gel

• A gel is a sol in which the solid particles have meshed such that a rigid or semi-rigid mixture results.
• An emulsion is a mixture of two or more liquids that are immiscible owing to liquid-liquid phase separation.
• Therefore, it is an example of an emulsion
• Hence option (C) is correct.

Option (D) Suspension

• A suspension is defined as a heterogeneous mixture in which the solid particles are spread throughout the liquid without dissolving in it.
• An emulsion is a mixture of two or more liquids that are immiscible owing to liquid-liquid phase separation.
• Therefore, it is an example of an emulsion
• Hence option (D) is correct.

Therefore, Milk is an example of option (A) Emulsion
