Kohlrausch law graphFor example, acetic acid is a weak electrolyte and its molar conductivity at infinite dilution can be calculated by Kohlrausch's Law. It can be represented as follows: μ ∞ = Molar conductance at infinite dilution μ ∞ = μ ∞ = m λ + ∞ + m λ − ∞ m and n are a number of ions formed.There is a simple demonstration of Kohlrausch's law. Start with four electrolytes with common ions, say AX, AY, BX and BY. The law says that the difference in limiting molar conductivities of two salts with a common ion is independent of that ion, for instance: Λ m ∘ ( A X) − Λ m ∘ ( A Y) = Λ m ∘ ( B X) − Λ m ∘ ( B Y)an equation that describes the molar conductivities of strong electrolytes at low concentration, i.e. λ m =λ 0m - κc½, where λ m is the molar conductivity, λ 0m is the limiting molar conductivity (the molar conductivity in the limit of zero concentration when the ions do not interact with each other), κ is a coefficient related to the …Kohlrausch's law states that the equivalent conductivity of an electrolyte at infinite dilution is equal to the sum of the conductances of the anions and cations. If a salt is dissolved in water, the conductivity of the solution is the sum of the conductances of the anions and cations.Wikipedia è un'enciclopedia online, libera e collaborativa..

Kohlrausch law of independent migration of ions states that the dissociation of an electrolyte is complete in the infinite dilution and thus the the ions that constitute the electrolyte contributes definitely. Thus the limiting equivalent conductivity of an electrolyte is the algebraic sum of the limiting equivalent conductivity of it's constituent ions.
