ABSTRACT:

The interaction of Co (II), Cu (II) and Ni (II) metal ions with 4-Amino-3-Naphthol-Sulphonic Acid (4A-3N-SA) and 6-Amino-5-Naphthol-Sulphonic Acid (6A-5N-SA) has been investigated pH metrically. It showed the formation of 1:1 and 1:2 complexes. The values of pK (proton-ligand stability constant) and logK (metal-ligand stability constant) at 0.1M ionic strength and 28 °C ± 0.1° were calculated.

KEYWORDS:

ph; metric studies; transition metal ions
