Question

What is the difference between multimolecular and macromolecular collids ? Give one example of each . How are associated colloids different from these two types of colloids ?

Answer 1

Difference between multimolecular and macromolecular colloids .

Multimolecular colloids are formed by the aggregation of a large number of simple molecules (e.g.`S_(8)`),
Macromolecular colloids are due to large size of the molecules themselves (e.g. starch) so large that their size lies in the colloidal range . However , associated colloids are formed by electrolytes so that they dissociate into ions and these ions associated together to form ionic micelles whose size lies in the colloidal range .e.g, soap .
