0.1 M HNO3 solution at 298K was electrolyzed in Hittorf cell using platinum electrodes. After electrolysis, 34.2 mg of copper was deposited in coulometer which in series with the Hittorf cell. 50 mL of HNO3 solution was withdrawn from anode compartment after electrolysis and found to have a concentration of 0.0821 M. [Atomic mass Cu = 63]. (i) Find the transference number of H + and NO3 −. (ii) If 50 mL HNO3 solution was run off from cathode compartment, what would its concentration be?
