Kohlrausch's law of independent migration of ions states that the limiting molar conductivity of an electrolyte equals:
AAlways 100 S cm² mol⁻¹
BThe product of cation and anion conductivities
CThe sum of the limiting molar conductivities of its constituent cations and anions
DThe difference between cation and anion conductivities
Answer & Solution
Correct answer: C. The sum of the limiting molar conductivities of its constituent cations and anions
**Kohlrausch's law**: Λ°_m (electrolyte) = ν₊ λ°₊ + ν₋ λ°₋. Each ion contributes its own limiting conductivity independently of the partner.
