Check An Ethylenediaminetetraacetic acid (EDTA) is an aminopolycarboxylic acid with the formula [CH2N(CH2CO2H)2]2. This white, water-insoluble solid is widely used to bind to iron (Fe /Fe ) and calcium ions (Ca ), forming water-soluble complexes even at neutral pH. It is thus used to dissolve Fe- and Ca-containing scale … See more Textile industry In industry, EDTA is mainly used to sequester (bind or confine) metal ions in aqueous solution. In the textile industry, it prevents metal ion impurities from modifying colours … See more The compound was first described in 1935 by Ferdinand Münz, who prepared the compound from ethylenediamine and chloroacetic acid. … See more In coordination chemistry, EDTA is a member of the aminopolycarboxylic acid family of ligands. EDTA usually binds to a metal cation through its two amines and four carboxylates, … See more Interest in environmental safety has raised concerns about biodegradability of aminopolycarboxylates such as EDTA. These concerns incentivize the investigation of alternative aminopolycarboxylates. Candidate chelating agents … See more EDTA exhibits low acute toxicity with LD50 (rat) of 2.0 g/kg to 2.2 g/kg.

WebLigands that bind via more than one atom are often termed chelating. A ligand that binds through two sites is classified as bidentate, and three sites as tridentate. Ethylenediamine is NH 2−CH 2−CH 2−NH 2 has the two donor atoms. So, it can bind with the central atom via two nitrogen atoms. So, it is a bidentate ligand. google translate english to greek textWebJul 28, 2009 · The complex formation of the type CuEdtaEn 2−, where En is ethylenediamine, has been studied earlier in the papers [1–6] mainly using NMR, EPR, IR and UV-visible spectroscopy.The authors of these works considered that En in mixed complex was bidentately coordinated due to decrease of chelate number (or denticity) … chicken legs air fryer recipesWebCommon examples of bidentate ligands are ethylenediamine (en), and the oxalate ion (ox).
