Vedclass · Answer

(A) Kohlrausch's law of independent migration of ions states that the limiting molar conductivity of an electrolyte is the sum of the limiting molar conductivities of its constituent ions,multiplied by their respective stoichiometric coefficients.For the electrolyte $A_2B$,it dissociates as follows:$A_2B \rightarrow 2A^+ + B^{2-}$Therefore,the limiting molar conductivity $\Lambda_m^\infty$ is given by:$\Lambda_m^\infty(A_2B) = 2\lambda _{A^+}^\infty + \lambda _{B^{2-}}^\infty$

According to Kohlrausch's law,what is the limiting molar conductivity of the electrolyte $A_2B$?
