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.
Some common chelating agents used in pools include EDTA (ethylenediaminetetraacetic acid), citric acid, and polyphosphates. These agents help bind metals like calcium and iron, preventing them from causing staining and scaling in pool water. Additionally, they can improve water clarity and overall balance. Using the right chelating agent can enhance the effectiveness of sanitizers and other pool chemicals.
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 .
Tertrasodium EDTA is a chelating and preservative agent.

chlorine is used as disinfactant and as a 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.
A chelating agent contains multiple sites capable of binding to a metal ion, forming a stable complex. These sites often have lone pairs of electrons that can coordinate with the metal ion. Chelating agents typically form a ring structure around the metal ion, enhancing the stability of the complex.
The primary cleaning agent used to clean pools is chlorine.
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.
A chelating agent in pharmaceutical compounding serves to bind metal ions, which can help stabilize formulations and enhance the efficacy of active ingredients. By sequestering potentially harmful metal ions, chelating agents can prevent degradation, improve solubility, and reduce toxicity. They are particularly useful in formulations where metal ion contamination may adversely affect the therapeutic effect or safety profile of the medication.
An aminodiphosphine is a compound containing an amino group and two phosphine groups, especially such a compound used as a chelating agent.
Sleneium is the main chelating agent in the selenium chelation process it is present in the human body normally in small quantities and can be used to extract mercury from the body helping to treat mercury poisoning.
