ABSTRACT:

The stability constants of Mn(II), Fe(II) and Zn (II) with p-Chloro Malonamic acid (PCMA), p-Amino Malonamic Acid (PAMA), p-Nitro Malonamic Acid (PNMA) different percentage of dioxane water has been determined pontentiometrically by Calvin-Bjerrum titrations. The titrations were carried out at constant ionic strength (0.1 M) and constant temperature i.e. 27±0.1°C. The data obtained can be used to study the values of porton-ligand and metal ligand stability constants for 1:1 and 1:2 complexes.
