Two weak acid solution HA1 and HA2 each with same concentration and having Pka values 3 and 5 are placed in contact with hydrogen electrode ( 1 atm at 25 degree) and are interconnected through a salt bridge find the emf.

Consider the cell:

                        Pt H2(1atm)IHA2(1M) II HA1(1M)IH2(1 atm)Pt

               Given that    PKa1 of HA1 is = 3 (at Cathode)

                                      Pka2 for HA2 is = 5 (at anode)
