What do you mean by chelating agent?

(KEE-lay-ting AY-jent) A chemical compound that binds tightly to metal ions. In medicine, chelating agents are used to remove toxic metals from the body. They are also being studied in the treatment of cancer.

What are chelating agents explain with example?

A chelating agent is a substance whose molecules can form several bonds to a single metal ion. An example of a simple chelating agent is ethylenediamine. ethylenediamine. A single molecule of ethylenediamine can form two bonds to a transition-metal ion such as nickel(II), Ni2+.

What is chelating agent in analytical chemistry?

Chelating agents are chemical compounds whose structures permit the attachment of their two or more donor atoms (or sites) to the same metal ion simultaneously and produce one or more rings.

What are chelating agents Class 12?

Chelation is a process in which a bidentate or a polydentate ligand binds to the metal atom to form a ring. The complex formed by this process is called a chelate. The polydentate ligand which leads to chelation is called a chelating agent.

Which is the best definition of a chelating agent?

Definition – What does Chelating Agent mean? A chelating agent is a chemical compound that reacts with metal ions to form stable, water-soluble metal complexes. The agent rearranges the metal’s chemical composition and improves the metal’s general stability and likelihood to bond with other substances.

How is chemical weathering related to chelating agents?

In geology. In earth science, chemical weathering is attributed to organic chelating agents (e.g., peptides and sugars) that extract metal ions from minerals and rocks. Most metal complexes in the environment and in nature are bound in some form of chelate ring (e.g., with a humic acid or a protein).

Which is an example of a chelating ligand?

Chelating ligand is a ligand which is mostly attached to a central metal ion by bonds that are from two or more donor atoms. In other words, these are a type of ligands where the molecules can form several bonds to a single metal ion or they are ligands with more than one donor site. Chelating ligands can have various attachment points.

How are organic compounds used in chelation therapy?

They are usually organic compounds . Chelation is useful in applications such as providing nutritional supplements, in chelation therapy to remove toxic metals from the body, as contrast agents in MRI scanning, in manufacturing using homogeneous catalysts, in chemical water treatment to assist in the removal of metals, and in fertilizers .
