What is the difference between multimolecular and macromolecular colloids? Give one example of each.

Text Solution

Verified by Experts


The common example of multimolecular colloid is sulphur sol, which consists of particles of `S_8` molecules. The common example of macromolecule is starch.
The associated colloids are substances which behave as normal electrolytes at low concentrations but behave as colloidal particles at higher concentration. For example, soap and detergents.
They differ from multimolecular and macromolecular colloids in the sense that they behave as normal electrolytes at low concentrations but exhibit colloidal state properties at higher concentrations due to the formation of aggregated particles called micelles.
