What are component of colloids?

Answer 1

A colloidal system consists of two separate phases: a dispersed phase (or internal phase) and a continuous phase (or dispersion medium). A colloidal system may be solid, liquid, or gaseous.

Answer 2

In a colloidal system you'll always talking about a dispersed phase in an continuous medium. These are the two components asked for.

Components of a colloidal 'solution' may be a fluid (eg. water) and a not-dissolved, very fine and not-aggregated solid particles (milk protein) that seem to stay stable (not settling down or floating up) in the liquid. The liquid is misty, tyndallising and not clear like a 'true' solution (sugar in water).

The same can be found in a gas (air) with liquid (water) called mist (not: rain) or with gas (air) with solid (cigarette smoke, micro-fine dust)

Foam, emulsion, gel, (solid or liquid aero-)sol are also some examples of the eight classes of Colloids.

Answer 3

A colloid is made up of tiny particles of one substance (dispersed phase) in another phase (dispersion medium). The dispersed phase particles are so small that they are virtually unaffected by gravity and remain in suspension indefinitely. Both phases of a colloid may be solid, liquid, or gas, except it is a gaseous mixture and not a colloid when one gas is dispersed in another gas.

Answer 4

Colloidal systems simply contain a dispersed phase and a dispersion medium. The dispersed phase particles are unaffected by gravity and remain in suspension.

Answer 5

The most common general names are the "dispersed phase" and the "continuous phase".

Answer 6

mixture and union
