What are Multimolecular colloids?

Define the following: Multimolecular colloids .

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?

Bt toxin protein exist in which form.

In multi-molecular colloids, the colloidal particles are an aggregate of atoms or small molecules with a diameter of less than 1 nm. The molecules in the aggregate are held together by van der Waal's forces of attraction: Examples of such colloids include gold sol and sulphur sol. In macro-molecular colloids, the colloidal particles are large molecules having colloidal dimensions. These particles have a high molecular mass. When these particles are dissolved in a liquid, sol is obtained. For example: starch, nylon, cellulose, etc. Certain substances tend to behave like normal electrolytes at lower concentrations. However, at higher concentrations, these substances behave as colloidal solutions due to the foirnation of aggregated particles. Such colloids are called aggregated colloids. What is the size of multimolecular colloids?

Based on type of particles of dispersed phase, give one example each of associate colloid and multimolecular colloid.
