Associated colloids, commonly known as micelles, exhibit unique concentration and temperature-depend — Surface Chemistry Chemistry Question

💡 Solution & Explanation

Statement A correctly describes surfactants acting as normal electrolytes before reaching the critical concentration. Statement B is false; micellisation is a highly cooperative thermodynamic binding process that occurs in a narrow region. Statement C gives the standard factual CMC range for soaps. Statement D correctly defines the thermodynamic necessity of exceeding the Kraft temperature.
