The formation of micelles (associated colloids) by surfactants like soaps and detergents occurs unde — Surface Chemistry Chemistry Question

💡 Solution & Explanation

Surfactants behave as normal strong electrolytes at low concentrations. They aggregate to form micelles (associated colloids) only when two specific conditions are met simultaneously: the concentration must exceed the Critical Micelle Concentration (CMC), and the temperature must be above the Kraft temperature ($T_k$).
