Question

The total number of coordination sites in ethylenediaminetetraacetate $\left({\mathrm{EDTA}}^{-4}\right)$ is

Answer 1

Ethylenediaminetetraacetate, $\left({\mathrm{EDTA}}^{-4}\right)$:

• Chromium $\left(\mathrm{Cr}\right)$, Iron $\left(\mathrm{Fe}\right)$, Lead $\left(\mathrm{Pb}\right)$, Mercury$\left(\mathrm{Hg}\right)$, Copper $\left(\mathrm{Cu}\right)$, Aluminum $\left(\mathrm{Al}\right)$, Nickel $\left(\mathrm{Ni}\right)$, Zinc $\left(\mathrm{Zn}\right)$, Calcium $\left(\mathrm{Ca}\right)$, Cobalt $\left(\mathrm{Co}\right)$, Manganese $\left(\mathrm{Mn}\right)$, and Magnesium $\left(\mathrm{Mg}\right)$ are just a few of the minerals and metals that EDTA attaches to and clings on to (chelates).
• When they are bound, they are separated from the body and are unable to have any impact on it.
• The coordination number assigned to EDTA is $6$.
• The coordinate number of the metal or ion refers to the number of ligand atoms that are directly connected to the core metal atom or ion by the coordinate bond.
• It is actually the quantity of chemical bonds that the ligand forms with the main metal atom or ion.
