The correct Answer is:
To determine which of the statements regarding micelle formation by soap in aqueous solutions are correct, we will analyze each option one by one. ### Step-by-Step Solution: 1. **Option (a): Micelle formation by soap in aqueous solution is possible at all temperatures.** - This statement is **incorrect**. Micelle formation occurs only above a specific temperature known as the Kraft temperature (TK). Below this temperature, micelles do not form. 2. **Option (b): Micelle formation by soap in aqueous solution occurs above a particular concentration.** - This statement is **correct**. Micelle formation occurs above a certain concentration known as the Critical Micelle Concentration (CMC). Below this concentration, the soap molecules do not aggregate to form micelles. 3. **Option (c): On dilution of soap solution, micelles may revert to individual ions.** - This statement is **correct**. When a soap solution is diluted, the concentration of soap decreases, and the micelles can break down, reverting back to individual ions in the solution. 4. **Option (d): Soap solution behaves as a normal strong electrolyte at all concentrations.** - This statement is **incorrect**. Soap solutions do not behave as strong electrolytes at all concentrations. They only exhibit strong electrolyte behavior above the Critical Micelle Concentration (CMC). Below this concentration, the behavior is different. ### Conclusion: - The correct options are **(b)** and **(c)**.
