The critical micelle concentration (CMC) of a soap solution is 5 10⁻⁴ ~mol ~L ⁻¹ . Identify the correct statements about this solution. I. The micelle is stable if the soap solution concentration is 10⁻⁷ ~mol ~L ⁻¹ II. The micelle is stable if the soap solution concentration is higher than 5 10⁻⁴ ~mol ~L ⁻¹ III. Micelles are also known as associated colloids.
