What are the applications of Kohlrausch's law ?

Explanation

The main application of Kohlrausch.s law are as follows :
i) Calculation of molar conductances at infinite dilution for weak electrolytes :
Molar conductance of weak electrolyte cannot be calculated at infinite dilution. It can be calculated with the help of molar conductances of strong electrolyte at infinite dilution.
ii) Calculation of degree of dissociation of weak electrolytes :
Degree of dissociation `(alpha)=("Molar conductance at given concentration"(wedge_(m)^(c)))/("Molar conductance at infinite dilution"(wedge_(m)^(@)))`
iii) Calculation of molar solubility of sparingly soluble salt :
Solubility `=(ĸxx1000cm^(3)L^(-1))/(wedge_(m)^(@))`
