Show ExplanationHide Explanation

Explanation

Kohlrausch’s law of independent migration of ions states that limiting molar conductivity is the sum of the individual limiting ionic contributions, weighted by the numbers of each ion in the formula unit: Λ°ₘ = ν₊λ°₊ + ν₋λ°₋. This is the infinite-dilution limit at a given temperature and in a given solvent.
