Applying Kohlrausch's law of independent migration of ions, the Λ0m value of water can be determined as follows:
Λ0m(H2O) = λ0H+ + λ0OH-
= (λ0H+ + λ0Cl-) + (λ0Na+ + λ0OH-) - (λ0Na+ + λ0Cl-)
Λ0m(HCl) + Λ0m(NaOH) - Λ0m(NaCl)
Hence, by knowing the Λ0m values of HCl, NaOH, and NaCl, the Λ0m value of water can be determined.
