Spectrophotometric Investigation of Complexation of Ferrous Ion with 3,5-Dintrosalicylic Acid
Abstract The determination of stoichiometry and stability constant of metal-ligand complex holds great significance for chemical, physical, environmental and biological studies. In the present work, the stoichiometric ratio and stability constant of iron complex of 3,5-dinitrosalicylic acid was determined using Job’s method of continuous variation. Job’s method can be easily […]
