ABSTRACT:

Interaction Co (II), Ni(II), Cu (II) & Zn (II) with Monopotassium salt of nitrilotriacetic acid and N-p-hydroxybenzalidine-2-aminopyridine have been made in solution at three different temps viz (15°C, 35°C, 45°C), was studied. PH titration data based on Ramamoorthy and Santappa method were employed for the calculation of mixed-ligand stability constants.
