Depending upon the type of the particles of the dispersed phase, colloids are classified as.

A

multimolecular colloids

B

macromolecular colloids

C

associated colloids

D

all of these

Text Solution

Verified by Experts

The correct Answer is:
D
Multimolecular colloids are formed when (on dissolution) a large number of atoms (or small molecules) of a substance aggregate together to form species having sixe in the colloidal range (diameter`lt1mm`). Macromolecular colloids are formed when macromolecules form solution (in suitable solvents) in which the size of the macromolecules lies in the colloidal range.
Associated colloids are those substance which behave as normal strong electrolytes at law concentratioons but exhibit colloidal behaviour (at higher concentrations) due to the formation of aggregates. The aggregated particles so formed are called micelles.
