An emulsion occurs when one liquid is dispersed in another liquid, and each liquid retains its original identity.

• A. True
• B. False
• C. Not sure
• D. Both

Answer: (A)

Emulsions are mixtures where one liquid is dispersed as tiny droplets within another liquid that the two liquids do not mix with. Because the two liquids stay as separate phases, each keeps its identity even though the droplets are dispersed throughout the other liquid. This is what defines an emulsion: a dispersed phase within a continuous phase of a different, immiscible liquid. For example, oil droplets in water form an emulsion, and the oil remains oil while the water remains water. Emulsifiers can help stabilize these droplets by reducing interfacial tension and creating a protective film around them, preventing droplets from coalescing. If the liquids were miscible and formed a single uniform phase, that would be a solution, not an emulsion. So the statement is true.
