The first and secondionization constants of phthalic acid have been determined, in formamide, attemperatures ranging from 5 to 45C at 5 intervals, with the help of cellswithout liquid junction using quinhydrone and silver-silver chlorideelectrodes. By means of the Bjerrum equation, thedistance r between the acidic groups has been estimated in formamide atdifferent temperatures.
