What is Kohlrausch Law?

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.

The molar conductivity of a solution at a given concentration is the conductance of the volume of solution containing one mole of electrolyte kept between two electrodes with the unit area of cross-section and distance of unit length. The molar conductivity of a solution increases with the decrease in concentration. This increase in molar conductivity is because of the increase in the total volume containing one mole of the electrolyte. When the concentration of the electrolyte approaches zero, the molar conductivity is known as limiting molar conductivity, Ëm°.

How to Calculate Kohlrausch Law?

Kohlrausch Law calculator uses Molar Conductivity = Limiting Molar Conductivity-(Kohlrausch Coefficient*sqrt(Concentration of Electrolyte)) to calculate the Molar Conductivity, The Kohlrausch Law states that the migration of an ion at infinite dilution is dependent on the nature of the solvent and on the potential gradient but not on the other ions present. Molar Conductivity is denoted by Λ_m symbol.
