Abstract

Physico-chemical studies of the complexes of 2-carboxyphenylhydrazoacetoacetanilide (2-CPHAAA) with Cu(II), Ni(II), Mn(II), and Co(II) ions in ethanol-water mixed solvent system

Potentiometric titrations have been used to calculate the dissociation constants of 2- Carboxyphenylhydrazoacetoacetanilide (2-CPHAAA) and its stability constants with Cu(II), Ni(II), Mn(II), and Co(II) ions in ethanol-water mixed solvent system at different temperatures, and constant ionic strength of 0.1M solution sodium nitrite.
