Question

What are colloids and their properties ?

Answer 1

Answer:

homogeneous non-crystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance. Colloids include gels, sols, and emulsions; the particles do not settle, and cannot be separated out by ordinary filtering or centrifuging like those in a suspension.

Physical Properties of Colloidal Solutions

Stability: Colloids are relatively stable in nature. The particles of the dispersed phase are in a state of continuous motion and remain suspended in the solution. Filterability: Colloids require specialized filters known as ultrafilters for filtration.

Answer 2

Explanation:

a a colloid is a heterogeneous mixture whose particles are not as small as solutionbut they are so small so they cannot be seen by naked eyeswhen a beam of light is passed through a colloid

then path of light becomes visiblevisible. for example milk smoke etc
