What is EDTA 2na?
Disodium EDTA EDTA Na2 (ethylenediaminetetracetic acid disodium) is a chelating agent, used to sequester and decrease the reactivity of metal ions that may be present in many industrial and personal care products.

What is the name of na2edta?
Ethylenediaminetetraacetic Acid, Disodium Salt (Na2-EDTA)
What is the difference between EDTA and EDTA disodium salt?
They are sodium salts of EDTA. Disodium EDTA has two sodium cations whereas tetrasodium EDTA has four sodium cations per molecule. The main difference between disodium EDTA and tetrasodium EDTA is that disodium EDTA has a pH lower than 7 whereas tetrasodium EDTA has a pH higher than 7.
Why is disodium salt of EDTA used?
1 Answer. The disodium salt of EDTA is preferred in hardness estimation mainly because it is more soluble in aqueous solutions which allows release of the EDTA ligand into solution to react.
What is EDTA full form?
Ethylenediamine tetraacetic acid (EDTA) is a polyprotic acid containing four carboxylic acid groups and two amine groups with lone-pair electrons that chelate calcium and several other metal ions.
What is full name and formula of EDTA?
Ethylenediaminetetraacetic acid (EDTA) is an aminopolycarboxylic acid with the formula [CH2N(CH2CO2H)2]2. This white, water-soluble solid is widely used to bind to iron and calcium ions. It binds these ions as a hexadentate (“six-toothed”) chelating agent.
How do you make 0.02 N EDTA solution?

Is EDTA same as Na2EDTA?
All Answers (6) Na2EDTA is EDTA, disodium salt dihydrate. Since it has two molecules of water, it should be easier to dissolve in water than anhydrous form. EDTA is every times complexed to one cation like Na.
How do you make Na2EDTA?
To prepare EDTA at 0.5 M (pH 8.0): Add 186.1 g of disodium EDTA•2H2O to 800 mL of H2O. Stir vigorously on a magnetic stirrer. Adjust the pH to 8.0 with NaOH (~20 g of NaOH pellets). Dispense into aliquots and sterilize by autoclaving.
What is the chemical formula of edta-2na?
Ethylenediaminetetraacetic acid disodium, also called EDTA-2Na, is a good compounding agent in chemistry. The chemical formula is C10H14N2Na2O8 and the molecular weight is 336.206. It has six coordinating atoms.
How much EDTA is produced by the nitric oxide process?
This process is used to produce about 80,000 tonnes of EDTA each year. Impurities cogenerated by this route include glycine and nitrilotriacetic acid; they arise from reactions of the ammonia coproduct.
What is the application of EDTA in biochemistry?
Laboratory applications. In the laboratory, EDTA is widely used for scavenging metal ions: In biochemistry and molecular biology, ion depletion is commonly used to deactivate metal-dependent enzymes, either as an assay for their reactivity or to suppress damage to DNA, proteins, and polysaccharides.
What is the geometry of EDTA 4-?
EDTA 4− usually binds to a metal cation through its two amines and four carboxylates. Many of the resulting coordination compounds adopt octahedral geometry. Although of little consequence for its applications, these octahedral complexes are chiral.
