Which of the following type of mixture is formed at Kraft Temperature?
-
Lyophobic colloids
-
Macromolecular colloids
-
Multimolecular colloids
-
Associated colloids
D
Correct answer
Explanation
Certain substances behave as strong electrolytes at low concentration but at higher concentrations these substances exhibit colloidal characteristics due to the formation of aggregated particles. These aggregated particles are called micelles. Micelles are called associated colloids. The formation of micelles takes place only above a particular temperature called Kraft Temperature (Tk) and above particular concentration called the Critical micelle concentration (CMC).
