What component of a dispersed system is the dispersed phase?

• A. distributed substance
• B. vehicle
• C. dispersion medium
• D. continuous phase

Answer: (A)

The dispersed phase is the material that is distributed throughout the system as droplets or particles. It’s the substance that appears dispersed within another medium. In a dispersed system, the “vehicle” or dispersion medium (also called the continuous phase) is what carries the dispersed phase, and the continuous phase is essentially the same idea as the dispersion medium. For example, in an oil-in-water emulsion, the oil droplets are the dispersed phase inside the water (the dispersion medium). In a suspension, solid particles are dispersed in a liquid. So the dispersed phase corresponds to the distributed substance.
