For soaps critical micelle concentration (CMC) is 10^(-x) (min) to 10^(-gamma) (max.) mol/L what is the value of x?

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?

each question constain STATEMENT-1(Assertion ) and STATEMENT - 2 (reason). examine the statement carefully and work the correct answer accoridng to the instructions given below : STATEMENT-1: Micelles are formed by surfactant molecules above the critical micelle concentartion (CMC). STATEMENT-2: The conductivity of a solution having surfactant molecules decrease sharply at the CMC.

Read the following passage and answer the questions. There are certain substances which behave as normal strong electrolytes at low concentration but at higher concentration they behave as colloidal solutions due to the formation of aggregated particles. Such colloids are called associated colloids and the aggregated particles are called micelles. Soaps and detergents are the examples of associated colloids. The formation of micelles takes place above certain concentration called critical micellisation concentration (CMC) and a characteristic temperature called Kraft temperature. What is the role of CMC in micelle formation ?
