Web10 nov. 2024 · 1. b L’ion Fe3+ possède une stabilité particulière par rapport à l’ion Fe2+ car la couche 3d de l’ion Fe3+ est à demi remplie. Une couche à demi remplie est stable car le spin y est maximal. Par conséquent l’ion Fe3+ ne peut que gagner des électrons. Qui est le plus électronégatif entre P et Cl? L’élément le plus électronégatif étant le Fluor. Web1 mei 1986 · In the present paper we demonstrate that another important 'antioxidant' property of uric acid is the ability to form stable co-ordination complexes with iron ions. Formation of urate-Fe3+ complexes dramatically inhibits Fe3+-catalysed ascorbate oxidation, as well as lipid peroxidation in liposomes and rat liver microsomal fraction.
