Question

What is the difference between multi-molecular and macromolecular colloids? Give one example of each.

Answer 1

Multimolecular colloids - They are formed by the aggregate of a large number of atoms or molecules which generally have diameters less than 1nm, e.g. Sols of gold, sulpher etc.
Macromolecular colloids - They are molecules of large size e.g. polymers like rubber, nylon, starch.
