The molar conductivity of a weak electrolyte increases quite sharply upon dilution primarily because the degree of electrolytic dissociation of the weak acid or base rises significantly as more solvent is added to the system. With this substantial increase in dilution, more unionized molecules dissociate into free, mobile ions, thereby significantly increasing the total number of charge carriers available per unit volume of the solution to conduct electricity effectively across the electrodes.
