Dispersed Phase vs. Dispersion Medium: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 27, 2023
Dispersed phase refers to the particles spread throughout a mixture, while dispersion medium is the substance in which these particles are dispersed.

Key Differences

The dispersed phase in a colloidal system is the component that consists of small particles or droplets distributed throughout another substance. In contrast, the dispersion medium is the substance in which these particles or droplets are distributed.

Particles in the dispersed phase can be solid, liquid, or gas, depending on the type of colloid. The dispersion medium, however, is typically a continuous phase of a different state, such as a liquid in which solid particles are dispersed.

The properties of a colloidal system are largely determined by the nature of the dispersed phase, such as its particle size and interaction with the dispersion medium. The dispersion medium, on the other hand, contributes to the stability and overall behavior of the colloid by interacting with the dispersed particles.

In many colloids, the dispersed phase is the minority component, whereas the dispersion medium is the majority component, giving the colloid its overall characteristics. However, the role of the dispersed phase is crucial in defining the colloid's specific properties, like color and viscosity.

Techniques like centrifugation and filtration can separate the dispersed phase from the dispersion medium, illustrating their distinct roles in a colloidal system. The interaction between the dispersed phase and dispersion medium can also be altered by changing temperature or adding substances that affect surface tension.
