%X The first and the second ionization constants of phthalic acid have been determined, in formamide, at 25° with the help of cells without liquid junction using quinhydrone and silver-silver chloride electrodes. The values of pK1a and pK2a were found to be 4.214±0.02 and 7.716±0.01, respectively, at this temperature.
