The interaction of Co(II), Sr(II), Pr(III) with methyl [-1-phenyl-3-(2’-hydroxy phenyl) pyrazole-5-carboxylate] has been studied at various ionic strengths pH metrically. The values of pk (proton-ligand stability constants) & log k (metal-ligand stability constants) are utilised to estimate the thermodynamic stability constants at zero ionic strength and to know the exact nature of complexation equilibria.
KEYWORDS:Stability constant; complexes; pyrazole derivatives
