Question

Kohlrausch's Law of Independent Migration of Ions asserts that at infinite dilution, each individual ion contributes a definite scalar amount to the total limiting molar conductance. Which of the following are direct theoretical and practical applications of this foundational law?

Answer: A,B,C

💡 Solution & Explanation

Kohlrausch's law allows calculation of $\Lambda_m^\circ$ for weak electrolytes via algebraic summation of strong electrolytes. Degree of dissociation is evaluated as $\alpha = \Lambda_m / \Lambda_m^\circ$. The solubility of sparingly soluble salts is determined assuming the saturated solution is at infinite dilution: $S = (1000 \times \kappa) / \Lambda_m^\circ$. The Faraday constant is related to charge, not derived from Kohlrausch's law.
