In general, for soaps, the concentration of surfactant at CMC is around \(\mathrm{mol} \mathrm{L}^{-1}\).
- A \(10^{-4}\) to \(10^{-3}\)
- B \(10^{-4}\) to \(10^{-1}\)
- C \(10^{-7}\) to \(10^{-4}\)
- D \(10^{-4}\) to \(10^{+2}\)
Answer & Solution
Correct Answer
(A) \(10^{-4}\) to \(10^{-3}\)
Step-by-step Solution
Detailed explanation
CMC is defined as concentration of surfactants above which micelles form and all additional surfactants added to the system will form micelles. Concentration of surfactant is nearly \(10^{-4}\) to \(10^{-3} \mathrm{~mol} \mathrm{~L}^{-1}\) at CMC. CMC depends on temperature,…
