Detailed Solution

The formation of micelles takes place only above a particular temperature called Kraft temperature (T_k) and above a particular concentration called critical micelle concentration (CMC). On dilution, these colloids revert to individual ions. Surface-active agents such as soaps and synthetic detergents belong to this class. For soaps, the CMC is 10^–4 to 10^–3 mol L^–1.
