Elsner complexation reaction
WebJul 4, 2024 · A hydrated ion is one kind of a complex ion (or, simply, complex), a species formed between a central metal ion and one or more surrounding ligands, molecules or ions that contain at least one lone pair of electrons, such as the [Al (H 2 O) 6] 3+ ion. A complex ion forms from a metal ion and a ligand because of a Lewis acid–base interaction. WebThis complexation has been applied to the elimination of toxic and carcinogenic Cr(VI) by ultrafiltration techniques [32]. The kinetics of the reactions of Cr(III) with EDTA and similar ligands [33,34] have been studied both in the absence and in the presence of hydrogen peroxide [35,36]. Although the Cr(III)-EDTA reaction under
