Stability Constants of Imidazole– and Alkylimidazole–Copper(II) Complexes

Spectrophotometric Study of Stability Constants of Metal Complexes of Promethazine at Different Temperatures

The complexation reactions between Cu2+, Pd2+ and Ni2+ metal ions with promethazine (PM) in water or DMF were studied by the spectrophotometric methods at [(15, 25,35 and 45±0.1) °C]. The complexation process was optimized in terms of pH, temperature and contact time. The stoichiometry of the complex was found to be 1:1 (metal ion/ligand). The formation constants of the resulting complexes were...

SPECTROPHOTOMETRIC STUDY OF THE STOICHIOMETRY AND CONDITIONAL STABILITY CONSTANTS OF SOME TRIVALENT METAL ION COMPLEXES OF METHYLTHYMOL BLUE

Complexation reactions between methylthymol blue and Fe , A l ,Ga , 1n a nd TI ions have been studied in buffer aqueous solutions of pH 5.0 at 2S°C by a spectrophotometric technique. The conditional stepwise stability constants of the resulting 1:l and 1:2 (metal-to-ligand) complexes were determined from the absorbance-mole ratio data at three different wavelengths of the visible sp...

Critical Evaluation of Equilibrium Constants in Solution Part A: Stability Constants of Metal Complexes CRITICAL SURVEY OF STABILITY CONSTANTS OF NTA COMPLEXES

Effective Analysis Associated with Stability Constants of Ternary Complexes

Concurrent equilibrium studies are of most extreme imperative to manage organic, medicinal and ecological issues emerging because of cutting edge specialized improvements. But in manufactured blends experienced in research facilities, metal ions or ligands never exist in secluded form requiring a top to bottom investigation of multi-metal and multi-ligand equilibria in solution. Accordingly the...
