Difference Between Dispersed Phase and Dispersion Medium

Thekey differencebetween dispersed phase and dispersion medium is that thedispersed phase is a discontinuous phase whereas the dispersion medium is a continuous medium.

A dispersion is a two-component system that consists of dispersed phase and dispersion medium. The dispersed phase has particles that distribute throughout the dispersion medium.

What is Dispersed Phase?

The dispersed phase of a dispersion is the discontinuous phase that distributes throughout the dispersion medium. It is one of the two components in acolloid. The particles of the dispersed phase have a diameter around 1-100 nm. There are three main types of particles;

1. Multimolecular Colloids

A multimolecular colloid has particles with low molecular weight. These small particles can combine with each other to form large particles having dimensions in the colloidal range. Ex: Sulphur solution. There are small S₈molecules that combine with each other to form large aggregates known as colloidal particles.

2. Macromolecular Colloids

Macromolecular colloids have particles with high molecular weight. These particles exist as individual particles in the dispersion. And these individual particles have dimensions in the colloidal range.

3. Associated Colloids

The dispersed phase of associated colloids has very small particles. These particles can aggregate to form colloids. Ex: soap and detergent in water.

What is Dispersion Medium?

分散介质的连续相colloid. Therefore, the dispersed phase distributes throughout the dispersion medium. Furthermore, this dispersion medium can be in any state of matter; solid state, liquid state or gas state.

Sometimes, the dispersion medium is also called theexternal medium因为它发生在分散阶段之外。例如，牛奶是一种胶体分散体，其中分散介质是水。另一个例子是雾。雾的分散介质是空气（水滴是分散相）。

概括– Dispersed Phase vs Dispersion Medium

分散相和分散培养基出现在相同的分散体中。分散相和分散介质之间的差异是分散相是不连续的相，而分散介质是连续的培养基。
