In a dispersed system, the medium surrounding the dispersed phase is called the dispersion medium.

In a dispersed system, the medium surrounding the dispersed phase is called the dispersion medium.

• A. Vehicle
• B. Dispersed phase
• C. Dispersion medium
• D. Coarse phase

Answer: (C)

In a dispersed system, the dispersion medium is the continuous surrounding phase in which the dispersed particles or droplets are distributed. It can be a liquid or a gas and determines how the dispersed phase behaves, including stability and flow properties. The dispersed phase refers to the particles or droplets themselves, not the surrounding medium. The term vehicle is a general carrier used in dosage forms and isn’t the precise label for the surrounding medium in this context, while the coarse phase is not a standard term for the surrounding medium.
