Which term describes a mixture where one liquid is dispersed as droplets in another liquid?

• A. Emulsions
• B. Suspensions
• C. Fumigants
• D. Solutions

Answer: (A)

Emulsions are mixtures in which tiny droplets of one liquid are dispersed throughout another liquid that they don’t dissolve in. In pesticides, an emulsifiable concentrate is mixed with water to form an emulsion, producing a cloudy mixture with oil droplets suspended in the water. Emulsifiers or surfactants help stabilize those droplets so they don’t rapidly separate. This is different from a solution, where the dissolved substance forms a single, uniform liquid, and from a suspension, where solid particles are dispersed in a liquid and may settle out. Fumigants are gaseous pesticides, not liquids dispersed as droplets.
