Difference Between Complexing Agent and Chelating Agent

The main difference between complexing agent and chelating agent is that complexing agent is an ion, molecule or a functional group that can bind with a metal ion through one or several atoms to form a large complex whereas a chelating agent is a compound that can bind with a metal ion to produce a chelate through ...

What is a complexing agent?

Complexing agents, or builders, are used in laundry detergent powders and liquids as well as in all-purpose cleaning agents. Commonly used complexing agents are phosphates, phosphonates, polycarboxylates, and zeolites. Complexing agents improve cleaning efficiency by inactivating water hardness.

Which is chelating agent?

Chelating agents are chemical compounds that react with metal ions to form a stable, water-soluble complex. They are also known as chelants, chelators, or sequestering agents. ... Specific chelating agents bind iron, lead, or copper in the blood and can be used to treat excessively high levels of these metals.

What are chelating agents examples?

The lead and other heavy metal chelators include succimer (dimercaptonol), dimercaprol (BAL), and ethylenediaminetetraacetic acid (EDTA). Succimer is orally available and appears to be more effective and better tolerated that the other therapies, which require intravenous administration.

What is the difference between chelate and complex?

A metal-containing ring like that shown is called a chelate ring (from the Greek chele, meaning “claw”). Correspondingly, a polydentate ligand is a chelating agent, and complexes that contain polydentate ligands are called chelate complexes.

What is a complexing agent used for?

Complexing agents are extensively applied in many fields of industry. They are used to provide effective controlling trace metal ions in cleaning industries, textile, pulp and paper production, water treatment, agriculture, food industries, etc.

What does a chelating agent do?

A chemical compound that binds tightly to metal ions. In medicine, chelating agents are used to remove toxic metals from the body.

What is a natural chelating agent?

Natural chelation therapy uses natural chelating agents like amino acids. Other organic acids like Acetic acid, citric acid, Ascorbic acid, lactic acid also acts as Natural chelating agents.

Is Vinegar a chelating agent?

The acid in vinegar (acetic acid) is a chelating agent.

Which is not chelating agent?

Oxalato, glycinato and ethylene diamine are large ligands and they can form rings because they all are bidentate ligands. So, they all are also chelating ligands. Thiosulphato is a monodentate ligand and hence, cannot form chelate rings. So, it is not a chelating ligand.

Are chelating agents safe?

The American College of Medical Toxicology and the American Academy of Clinical Toxicology warn the public that chelating drugs used in chelation therapy may have serious side effects, including liver and kidney damage, blood pressure changes, allergies and in some cases even death of the patient.

What makes a good chelating agent?

An ideal chelator should have high solubility in water, resistance to biotransformation, ability to reach the sites of metal storage, retain chelating ability at the pH of body fluids and the property of forming metal complexes that are less toxic than the free metal ion (Figure 2).

What are chelating agents in shampoo?

Chelating agents are used in small amounts to react with metal ions present in hair care products or in the water, in order to improve stability or performance of the product.
