What is the coordination of EDTA?

six
It is a hexadentate ligand, which means a single molecule can occupy six stereochemical positions around a metal atom. Hence, the coordination number of EDTA is six.

What is the full name and structure of EDTA?

Ethylenediaminetetraacetic acid (EDTA) is an aminopolycarboxylic acid with the formula [CH2N(CH2CO2H)2]2. This white, water-soluble solid is widely used to bind to iron and calcium ions.

Is EDTA a coordination compound?

coordination compounds Ethylenediaminetetraacetic acid (EDTA) forms very stable complexes, and it is widely used for this purpose.

What is the coordination number of EDTA and draw its structure?

The coordination number for EDTA is 6. The coordinate number of the metal or ion is the number of ligand atoms that are directly attached to the core metal atom or ion by the coordinate bond. It’s the number of chemical bonds formed between the ligand and the core metal atom or ion.

What is EDTA in biochemistry?

A chemical that binds certain metal ions, such as calcium, magnesium, lead, and iron. It is used in medicine to prevent blood samples from clotting and to remove calcium and lead from the body. It is also used to keep bacteria from forming a biofilm (thin layer stuck to a surface).

What is EDTA tube?

VACUETTE® EDTA tubes are used for determinations in EDTA whole blood for haematology, immunohaematology or for the molecular biological identification of viruses, parasites and bacteria after centrifugation and plasma for clinical chemistry.

What is the geometry of Ca EDTA complex?

Figure 6 presents the molecular structure of the Ca-EDTA complex. In the complex, EDTA acts as a hexadentate unit by wrapping itself around the metal ion with four oxygen atoms and two nitrogen atoms and forms several five-member chelate rings. …

What is a calcium chelator?

Chelators are compounds that bind to metal ions forming a complex and some of them are also fluorescent. If the complex has fluorescence properties different from those of the free chelator, it can be used as an ion indicator.
