Abstract

The dissociation constant pKa of acetylacetone has been determined potentiometrically. The pKa value obtained is 9.40, indicating a weak acid. The stability constants of the complex compounds formed from the reaction of nickel (II) and copper (II) with acetylacetone determined using potentiometer are 6.32x10 15 and 2.82x10 14 , respectively. Similarly, the number of acetylacetonato ligands coordinated to each metal ion determined potentiometrically is 3.
