A hittorf cell filtered with Ag/Agcl electrode is filled with Hcl solution that contain 0.3856×10–3gHcl/g water. A current of 2.00A is passed for exactly 3hours.the solution are withdraw,weight and analysed.the total weight of a cathode solution is 51.7436g,it contains 0.0267g of Hcl.the anode solution weight 52.0461g and contains 0.0133g of Hcl.what is the transference number of the H ion?

The numerical value of the Faraday constant is given as 96,500. This value represents
the number of coloumbs of charge carried by one mole of
electrons.
the number of electrons corresponding to one coloumb of
charge.
the number of electrons corresponding to one mole of
electric charge.
the number of ions discharged by the passage of one mole
of electrons.
96,500 amp/sec.
