Question

Milk is an example of water in oil emulsions

• A. True
• B. False
• C. Ambiguous
• D. Data insufficient

Answer 1

The correct option is B

False

The explanation for Correct answer:

Option B false

• 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 into a liquid that is the emulsion.
• On the basis of the properties of the dispersed phase and the dispersion, medium Emulsions can be classified into two, Oil in water emulsion and Water in oil emulsion
• In the oil in water(o/w) type of emulsion, the oil will be the dispersed phase and water will be the dispersion medium.
• The best example of o/w emulsion is milk in which the fat globules (act as the dispersed phase) are suspended in water (act as the dispersion medium).
• In Water in the oil(w/o) type, water will be the dispersed phase and oil will be the dispersion medium.
• The best example of w/o emulsion is Margarine (a spread used for flavouring, baking, and working).
• Hence option (B) False is correct.

The explanation for incorrect answers:

Option A True

• In milk, the fat globules (act as the dispersed phase) are suspended in water (act as the dispersion medium).
• So, milk is an example of the oil in water(o/w) type of emulsion.
• Hence option A is incorrect.

Option C Ambiguous

• The milk is an example of the oil in water(o/w) type of emulsion.
• In milk, the fat globules (act as the dispersed phase) are suspended in water (act as the dispersion medium).
• Hence option C is incorrect.

Option D Data insufficient

• The milk is of oil in water(o/w) type emulsion.
• In which, the fat globules (act as the dispersed phase) are suspended in water (act as the dispersion medium).
• Hence option D is incorrect.
