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 ?

Explanation

`a.` Multimolecular colloids are formed by the aggregation of small molecules `(` diameter `lt1mm)`, while macromolecular colloids are forced by macromolecular and consist of single molecules.
`b`. Multimolecular colloids are generally lyophobic whereas macromolecular colloids are generally lyophilic.
Difference between associated colloids and multimolecular and macromolecular colloids.
Multimolecular colloids are formed by the aggregation macromolecular colloids are due to the 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 associate together to form ionic micelles whose size lies in the colloidal range, `e.g.,` soaps. This happens above a particular concentration `(` called critical micellization concentration `)` and above a particular temperature, called Kraft temperature.
