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 Kraft temperature in micelle formation ?
