Potentiometric Studies of Some Binary Complexes of Fe(II) with Ligands Containing Coumarin Moiety
Keywords:
Ferric(III) ions, Binary complexes, Stability constants, pH Metric titration.Abstract
Thepresent paper describes the studyof the complex formation of Ferric(III) ion with the chalcones derived from 3-acetyl- 4-hydroxy-6-methyl-coumarin and cinnamaldehyde, 3,4-dimethoxybenzaldehyde and 2-nitrobenzaldehyde.Thestability constant oftheir complexes with Ferrousic(III) ions, have been studied by using Irving-Rossotti method at constant temperature 300 ±10Cand ionic strength µ= 0.1 M dm-3.
