Kohlrausch's Law, , The law states that “Limiting molar conductivity (A’,,) of an electrolyte can be, represented as the sum of the individual contributions of anion and cations of the, electrolyte.” For example: The limiting molar conductivity of electrolyte NaCl is, the sum of limiting molar conductivities of Na” ion and CI ion., , A’ (NaCl) = 4'Na* + 2°C, , , , )-Na* = Limiting molar conductivity of Na* cation, , CY = Limiting molar conductivity of Cl anion., If an electrolyte give v’ cations and v anions on dissociation then its limiting molar, conductivity is given by:, , Na=Vv Nat tv Cr
