This is known as Kohlrausch 's law of independent ionic migration. [7] For any electrolyte A x B y, the limiting molar conductivity is expressed as x times the limiting molar conductivity of A y+ and y times the limiting molar conductivity of B x−. Kohlrausch 's law states that at infinite dilution of the solution, each ion of electrolyte migrates independently of its co-ions and contribute independently to the total molar conductivity irrespective of the nature of other ion. Kohlrausch law states that the equivalent conductance of an electrolyte at infinite dilution is equal to the sum of the individual conductance of anions and cations. Learn how to calculate the limiting molar conductivity, dissociation constant, solubility constant and cell potential using this law with examples and FAQs. Learn about Kohlrausch 's law , which states that the limiting molar conductivity of an electrolyte is the sum of the conductances of its ions. Find out how to apply this law to calculate dissociation constants, degrees of dissociation and solubilities of weak electrolytes.
