Answer 2

Answer:

Chelating agents—ligands capable of forming two or more coordinating covalent bonds with a metal ion—are an essential and fascinating example of this.

Explanation:

Chelation bonding:

• Chelation occurs when numerous coordination interactions form between organic molecules and a transition metal ion, causing the metal to be sequestered.
• When a metal cofactor is involved, this activity is exceedingly common in the body and a fundamental component of enzyme performance (eg, hemoglobin).

Chelation agent used in metal extraction:

• NTA (C6H9NO6) is a polyamino carboxylic acid that is also used as a chelating agent, forming coordination compounds (chelates) with metal ions like Ca2+, Cu2+, and Fe3+. NTA is used in a similar way to EDTA.

How Chelation works?

• Chelators bind to metals in the bloodstream and then release them. They circulate through the bloodstream, attaching to metals, after being administered into the bloodstream.
• Chelators gather all heavy metals into a substance that is filtered via the kidneys and excreted in urine in this way.
