N2  - The cells                    Ag-AgCl|KCl(m3), KOBz(m2), HOBz(m1), QH2-Q|Pt   and                           Hg-Hg2(OBz)2|HOBz(m), QH2-Q|Pt   have been used to redetermine the ionization constant of benzoic acid in formamide and the standard potential of the Hg-Hg2(OBz)2 electrode in formamide at 25°. The ionization constant of benzoic acid is found to be 4.79 x 10-7 and is in good agreement with the value 4.37x10-7 obtained earlier. The value 0.2535±0.0005 V for the standard potential of the Hg-Hg2(OBz)2 electrode is in good agreement with the values 0.2541±0.0003 and 0.2545±0.0005 V obtained previously from two independent cells.
