Popis:	Summary The dissociation of itaconic acid was investigated potentiometrically at ionic strength I =1 in NaClO 4 at 25.000±0.02°C in the concentration range 0–50 m M . The two dissociation constants were calculated by both a graphical and a computer method. The values reported are p K A 1 =3.629±0.002 and p K A 2 =4.988±0.0001. For concentrations > 50 m M , polynuclear proton itaconate complexes are observed.
