Question

Milk is colloid in which

• A. a liquid is dispersed in the liquid
• B. a solid is dispersed in the liquid
• C. some sugar is dispersed in water
• D. a gas is dispersed in the liquid

Answer 1

The correct option is A

a liquid is dispersed in the liquid

Explanation for Correct answer:

Option A liquid is dispersed in the liquid

• 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(emulsion).
• 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 answers:

Option B a solid is dispersed in the liquid

• Milk is a colloid in which a liquid is dispersed in a liquid.
• Hence option (B) is incorrect.

Option C some sugar is dispersed in water

• Milk is a colloid in which a liquid is dispersed in a liquid.
• Hence option (C) is incorrect.

Option D some sugar is dispersed in water

• Milk is a colloid in which a liquid is dispersed in a liquid.
• Hence option (D) is incorrect.

Therefore, Milk is colloid in which option (A) a liquid is dispersed in the liquid
