The first and second ionization constants of phthalic acid have been determined, in formamide, at temperatures ranging from 5� to 45�C at 5� intervals, with the help of cells without liquid junction using quinhydrone and silver-silver chloride electrodes. By means of the Bjerrum equation, the distance r between the acidic groups has been estimated in formamide at different temperatures.
