Question

Molar conductivity (Λm) of an aqueous solution of sodium stearate, which behaves as a strong electrolyte, is
recorded at varying concentrations (c) of sodium stearate. Which one of the following plots provides the
correct representation of micelle formation in the solution?
(critical micelle concentration (CMC) is marked with an arrow in the figures)

Solution

The correct option is B
We know that with the increase in concentration of the electrolyte, the molar conductivity decreases. Beyond CMC, the ions gets associated and form micelles. So the number of charge carriers decreases even further and hence beyond CMC, the molar conductivity decreases more abruptly.
