Define Kohlrausch’s law


The equivalent conductivity of an electrolyte at infinite dilution is equal to the sum of the conductances of the anions and cations, according to Kohlrausch’s law.
The conductance of a volume of solution containing one mole of electrolyte retained between two electrodes with the unit area of cross-section and distance of unit length is the molar conductivity of a solution at a certain concentration. The molar conductivity of a solution rises as the concentration falls. The increase in total volume containing one mole of the electrolyte causes the rise in molar conductivity. The molar conductivity is known as limiting molar conductivity, as the electrolyte concentration approaches zero.
The equivalent conductivity of an electrolyte at infinite dilution is equal to the sum of the conductances of the anions and cations, according to Kohlrausch’s law. The conductivity of a solution is equal to the total of the conductances of the anions and cations when a salt is dissolved in water.
