Kohlrausch's law states the limiting molar conductivity of an electrolyte is:
AAlways equal
BSum of individual ionic limiting conductivities
CProduct of conductivities
DVariable with concentration
Answer & Solution
Correct answer: B. Sum of individual ionic limiting conductivities
Kohlrausch's law: Λ_m^0(electrolyte) = ν+ λ+^0 + ν- λ-^0, where ν+ and ν- are cation and anion stoichiometries. Λ_m^0(HCl) = λ_H+^0 + λ_Cl-^0.
