Hi..
i) Determination of for weak electrolytes : The molar conductivity of a weak electrolyte at infinite dilution cannot be determined by extrapolation method. However, values for weak electrolytes can be determined by using the Kohlrausch's equation.
ii) Determination of the degree of ionisation of a weak electrolyte: The Kohlrausch's law can be used for determining the degree of ionisation of a weak electrolyte at any concentration. If is the molar conductivity of a weak electrolyte at any concentration C and, is the molar conductivity of a electrolyte at infinite dilution. Then, the degree of ionisation is given by,
Thus, knowing the value of , and (From the Kohlrausch's equation), the degree of ionisation at any concentration can be determined.
Hope this helps u!!
