What component of a dispersed system is the dispersing phase or dispersion medium?

What component of a dispersed system is the dispersing phase or dispersion medium?

• A. vehicle
• B. distributed substance
• C. dispersed phase
• D. coarse phase

Answer: (A)

In a dispersed system, there are two parts: the phase that is dispersed (the dispersed phase) and the medium that carries and surrounds it (the dispersion medium). The dispersion medium, also called the vehicle, is the continuous phase in which the dispersed particles are distributed. It largely determines the system’s rheology, solubility, and stability. So the component that serves as the dispersing medium is the vehicle. For example, in a suspension, water or another liquid acts as the vehicle; in an oil-in-water emulsion, the water is the dispersion medium, while the oil forms the dispersed phase.
