Question

define the following macromolecular colloids and associated colloids?​

Answer 1

Answer:

Macromolecular colloids: When certain substances having big size molecules, called macromolecules , having large molecular masses are dissolved in a suitable liquid, they form a solution in which the molecules of the substance i.e the dispersed particles have size in the colloidal range. Such substances are called macromolecular colloids.Example: Starch, nylon

Associated colloids are the substances which when dissolved in a medium at low concentrations behave as normal strong electrolytes but at higher concentrations exhibit colloidal state due to the formation of aggregated particles are called associated colloids. The associated colloids are called as micelles. Example: Soaps
