Notes:
The condensation of acetylacetone with anthranilic acid in presence of piperidine as the condensing agent gives acetylacetoneanthranilic acid SCHIFF'S base (H2AA) which forms complexes with Zinc (II) and Palladium (II). The dissociation constants of H2AA have been determined by interpolation at half n̄ values and also by algebraic method which give the values 4.85 and 8.25 at 30° ± 1 °C for the dissociation constants. The stability constants of Zinc (II) and Palladium (II) complexes have been determined adopting CALVIN and MELCHIOR'S extension of BJERRUM'S method and the values of log k1 are found to be 2.92 and 3.97 respectively at 30° ± 1 °C. In these complexes 1:1 metal-ligand stoichiometry is observed.
