Key Idea According to Kohlrausch's law, $${\lambda }_m^0\text{ for }{A}_x{B}_y=x{\lambda }_{(A{)}^{0+}}^0+y{\lambda }_{(B{)}^{x-}}$$ where, ${\lambda }_m^{\circ }=$ limiting molar conductivity of electrolyte and ${\lambda }_{(A{)}^{y+}}^0$ and ${\lambda }_{(B{)}^{x-}}^0$ are the limiting molar conductivities of cation $\left(A^{y+}\right)$ and anion $\left(B^{x-}\right)$, respectively.
