Kohlrausch's law of independent migration of ions is used to compute

Question

Accepted Answer

B. {'text': 'Limiting molar conductivity of weak electrolytes', 'label': 'B'}

1. Kohlrausch law: at infinite dilution, each ion contributes independently to conductance.
2. Limiting molar conductivity Λ°_m of a salt equals the sum of cation and anion contributions.
3. For weak electrolytes where direct extrapolation is not possible, we use strong-electrolyte values.
4. Example: Λ°_m(CH₃COOH) = Λ°_m(CH₃COONa) + Λ°_m(HCl) − Λ°_m(NaCl).
