Question

EDTA is ________ ligand.

Answer 1

Hint- EDTA is an incredible chelating agent, permitting multiple bindings in a coordination complex. This enables it to displace other unwanted ligands because of entropy and thermodynamics, and is in this manner utilized in labs, processing plants, and in medication. The issue with its abuse is that it debases into a poison. By having abundance of this, more poison is made and left in the environment.

Complete answer:
EDTA is a hexadentate ligand, which implies that it binds multiple (six) times. It binds twice at the nitrogen and four at the oxygens.
Apart from its helpfulness in enterprises, EDTA can likewise be used in medication. Specialists can recommend EDTA medicines for patients experiencing lead poisoning. Such a treatment is known as chelation treatment, in which EDTA renders the poisonous particles present in the body innocuous. The EDTA is administered intravenously and clears its path through the circulation system. Given its hexadentate nature, EDTA has an atomic structure a lot like a claw. In view of this very structure, the EDTA pulls harmful substantial metals recognized in the circulation system towards itself and joins itself to these metal particles. This connection frames an aggravate that can be discharged from the body through pee, not permitting them to bind to chemicals and cytochromes. A chelation treatment may take numerous sittings and may last somewhere in the range of one to three hours for each sitting. Not exclusively can chelation treatment help in discharging destructive lead particles from the body, however it can likewise help in securely disposing of mercury, chromium, cobalt, nickel, zinc, arsenic and thallium particles from the circulatory system.

Thus, EDTA is a hexadentate ligand.

Note: In instances of abundance utilization of digoxin, a drug used to treat atrial fibrillation, atrial flutter and even cardiovascular breakdown, EDTA has been utilized to free the circulation system from the unused ions.
