WebMay 1, 2008 · In the green bean experiment, control (no chelate applied) plants showed important micronutrient deficiency symptoms and growth reduction, while IDHA treated plants were healthy. Although EDTA provides micronutrients in higher amounts than IDHA, a chryptogamic infection was observed for this treatment but not for the IDHA one. 1) Cu 2+ + 2 MeNH 2 ⇌ [Cu(MeNH 2) 2] 2+ (2) In (1) the ethylenediamine forms a chelate complex with the copper ion. Chelation results in the formation of a five-membered CuC 2 N 2 ring. In (2) the bidentate ligand is replaced by two monodentate methylamine ligands of approximately the same … See more Chelation is a type of bonding of ions and molecules to metal ions. It involves the formation or presence of two or more separate coordinate bonds between a polydentate (multiple bonded) ligand and a single central metal … See more Numerous biomolecules exhibit the ability to dissolve certain metal cations.

A representative example is the use of BINAP (a bidentate phosphine) in Noyori asymmetric hydrogenation See more The word chelation is derived from Greek χηλή, chēlē, meaning "claw"; the ligands lie around the central atom like the claws of a lobster. The term chelate was first applied in 1920 by Sir Gilbert T. Morgan and H. D. K. Drew, who stated: "The adjective chelate, … See more The chelate effect is the greater affinity of chelating ligands for a metal ion than that of similar nonchelating (monodentate) ligands for the same metal. The thermodynamic principles underpinning the chelate effect are illustrated by the … See more Nutritional supplements In the 1960s, scientists developed the concept of chelating a metal ion prior to feeding the element … See more Dechelation (or de-chelation) is a reverse process of the chelation in which the chelating agent is recovered by acidifying solution with a mineral acid to form a precipitate.
