A ligand is an ion or molecule that binds to a central metal atom to form a coordination complex. The bonding usually involves the formal donation of one or more of the ligand's electron pairs. A chelating agent is a type of ligand.

What are the differences between dehydrating agent and chelating agent?
A dehydrating agent is usually an acid which brings about loss of water molecule when used on an hydrated compound. A chelating agent is usually an electron donour (ligand) which forms a complex by coordinating with a metal using two or more donor groups of a single ligand.
Is chelating agent negatively charged?
Not necessarily. Chelating agents can be neutral too. For example en (ethylenediamine), etc. The only condition for a ligand to be called a chelating agent is that it should coordinate with the metal in a manner so as to form a ring .
Is EDTA hexadentate ligand or tetradentate?
It is hexadentate strong field ligand a polydentate ligand is also known as chelating agent because it forms chelate like structure around the central metallic ion.
How can cheating agents act as antioxidants?
A cheating agent has a crab-claw-like ligand which coordinates to the metal ion. This decreases the concentration of free transition metals in solution so there is less chance of oxidation. An example of a chelating agent is the rosemaric acid.Chelating agents (such as EDTA) chelates the divalent metal ions such as Mg2+ or Zn2+
Name some chelating agents?
One natural chelating agent is tannic acid.
What the function of chelating agent in yeast cells?
entah
What is tertrasodium edta?
Tertrasodium EDTA is a chelating and preservative agent.
Tris EDTA buffer in plant DNA isolation?
Chelating agent
What would happen if you did not use a chelating agent?
You will have free metal ions.
Give alternative uses of chlorine?
chlorine is used as disinfactant and as a chelating agent
What is a chelating agent for pools?
A chelating agent (also known as a complexing or sequestering agent) is a compound that forms stable complexes with metal ions. Control of metal ion activity in aqueous systems is the main use of chelating properties so precipitation of sparingly soluble salts such as those of of calcium and magnesium with inorganic anions, fatty acids and anionic surfactants can be avoided. Typical applications are scale control and water softening.
What is use of Versene in inorganic chemistry?
Versene is a trade name for a chelating agent, a sodium salt of EDTA, ethylenediaminetetraacetic acid. This molecule is a polydentate ligand with 6 points where it can coordinate to a central metal ion. It binds readily to many cations and is used in the laboratory in complexometric titrations. It has many applications in for example medicine and industry.
