Popis:	Dissociation constants (pK a ) of acetic, oxalic, citric, and ethylenediaminetetraacetic acids have been determined potentiometrically using a hydrogen ion glass electrode at 25 °C in solutions of ionic strengths ranging from 0.3 to 5.0 m NaCl. The observed ionic strength dependencies of the pK a values have been described successfully over the entire ionic strength range using both the Specific Ion Interaction Theory and the Pitzer model. The variation of the pK a values at high ionic strengths with the type and concentration of supporting electrolyte is discussed and compared to literature data.
