Colloidal sol of sulphur is an example of multimolecular colloid while colloidal sol of starch represents macromolecular colloid. Difference between associated colloids, multimolecular and macromolecular colloids. Multimolecular colloids are formed by the aggregation of a large number of simple molecules, macromolecular colloids consists of macromolecules having size in the colloidal range. On the other hand, associated colloids also called micelles, are generally electrolytes. They exist as ions at low concentration. However, above a particular concentration called critical micelle concentration (CMC) and above a particular temperature called Kraft temperature, these get associated and exhibit colloidal behaviour. Soap is a common example of associated colloids. Define multimolecular colloid?
