Question
46. Which equation correctly establishes the solubility ($S$ in mol/L) of a sparingly soluble salt using its saturated specific conductance ($\kappa$) and limiting molar conductivity ($\Lambda^\circ_m$)?
Answer: B
💡 Solution & Explanation
A saturated sparingly soluble salt is assumed to be at infinite dilution ($\Lambda^c_m \approx \Lambda^\circ_m$). Starting from $\Lambda_m = (\kappa \times 1000) / M$, we substitute Molarity ($M$) with Solubility ($S$) to get $S = (\kappa \times 1000) / \Lambda^\circ_m$.
