Abstract

Study of equilibrium constants of 5-ASA with transition metal ions

Potentiometry is one of the most convenient and successful technique employed for metal complex equilibrium measurements. In the present work, the interactions of transition metal ions Mn(II) and Co(II) with 5-ASA has been investigated in double distilled water mixture at 0.2 M ionic strength at temp 30 °C + 1.00C by potentiometrically. Proton ligand (pK) and metal-ligand (logK) stability constant were determined by using Calvin Bjerrum titration technique as modified by Irving & Rossoti.
