The transference number of the hydrogen ion in an aqueous solution containing HCl and NaCl is 0.5. The limiting molar conductivities of H+, Na+ and Cl− are, respectively, 350 × 10−4 S m2 mol−1, 50 × 10−4 S m2 mol−1 and 75 × 10−4 S m2 mol−1. The ratio of the concentrations of HCl and NaCl, namely [HCl][NaCl] is
