State Kohlrausch law for electrical conductance of an electrolyte at infinite dilution.

Explanation

At infinite dilution, the molar conductance of an ion is independent of the nature of the other ion with which it is associated in the electrolyte and the limiting conductance `(wedge_(m)^(oo))` of an electrolyte is the sum of limiting molar conductances of its cation and anion.
`wedge_(m)^(oo) =lambda_(+)^(oo) +lambda_(-)^(oo) or lambda_(m)^(oo)=v_(c )lambda_(c )^(oo)+v_(a)lambda_(a)^(oo)`
