N2  - The first and second ionization constants of the dicarboxylic oxalic, malonic, succinic, glutaric and adipic acids in formamide have been determined at nine temperatures ranging from 5 to 45°, using cells of type:                        Pt, H2|H2A(m1), KHA(m2), KCl(m3)|AgCl-Agand                     Pt, H2|KHA(m1), K2A(m2), KCl(m3)|AgCl-Ag  respectively, where H2A stands for dicarboxylic acids, KHA for mono- potassium salts and K2A for potassium salts of dicarboxylic acids. These values have been utilized to evaluate the standard thermodynamic quantities &#916;G°, &#916;H° and &#916;S° associated with the first and second ionization processes at 25°.
