Ethylenediaminetetraacetic acid
Ethylenediaminetetraacetic acid is a kind of organic compound. The formula is C10H16N2O8. It can act as a six-membered ligand and binds to metal ions to form chelate compounds with chiral properties. EDTA can be simultaneously coordinated to the six corners of the octahedral centered on the metal ion, so that the central metal is surrounded by the ligand. Thus, EDTA has a strong affinity for certain metal ions. It is present as white crystals or powder. It decomposes at 245 ° C. The molecular weight is 292.24 and the density is 0.86 g / cm3. It can act as a speculative asset.
