POTENTIOMETRIC STUDIES OF P-AMINO BENZOIC ACID WITH TRANSITION METAL IONS
Sayyed Hussain , Shaikh Abdul Rahim , Mazahar Farooqui
ABSTRACT
The aim of our study is to investigate the complexation tendency and
stability values of transition metal ions with 4-amino benzoic acid in
aqueous media at room temperature using simple technique of
potentiometry.1N NaNO3 used to maintain ionic strength. The stability
constants were evaluated by computer programme.1:1 and 1:2
complexes were reported. Order of stability was compared and found
to follow Irving William natural order.
Keywords: Complexation, Stability constants
