EDTA is ethylenediamine tetraacetic acid. It's a strong chelating agent. It has many uses including:
- Industrial cleaning: complexation of Ca2+ and Mg2+ ions, binding of heavy metals.
- Detergents: complexation of Ca2+ and Mg2+ (reduction of water hardness).
- Photography: use of Fe(III)EDTA as oxidizing agent.
- Pulp and paper industry: complexation of heavy metals during chlorine-free bleaching, stabilization of hydrogen peroxide.
- Textile industry: complexation of heavy metals, bleach stabilizer.
- Agrochemicals: Fe, Zn and Cu fertilizer, especially in calcareous soils.
- Hydroponics: iron-EDTA is used to solubilize iron in nutrient solutions.
More specialised uses of EDTA are:
- Food: added as preservative to prevent catalytic oxidation by metal ions or stabilizer and for iron fortification.[citation needed]
- Approved by the FDA as a preservative in packaged foods, vitamins, and baby food.
- Personal care: added to cosmetics to improve product stability.[citation needed]
- Oil production: added into the borehole to inhibit mineral precipitation.[citation needed]
- Dairy and beverage industry: cleaning milk stains from bottles.[citation needed]
- Flue gas cleaning: removal of NOx.
- Dentistry as a root canal irrigant to remove organic and inorganic debris (smear layer).[citation needed]
- Soft drinks containing ascorbic acid and sodium benzoate, to mitigate formation of benzene (a carcinogen).[citation needed]
- Recycling: recovery of lead from used lead acid batteries.
Medicine:
- EDTA is used in chelation therapy for acute hypercalcemia, Mercury poisoning and lead poisoning[4].
- Combined with chromium, EDTA is used to evaluate kidney function. It is administered intravenously and its filtration into the urine is monitored. This method is considered the gold standard for evaluating glomerular filtration rate, Cr-EDTA's sole way out of the body is via glomerular filtration as it is not secreted or metabolised in any other way.
- Used as anticoagulant for blood samples
- In veterinary ophthalmology EDTA may be used as an anticollagenase to prevent the worsening of corneal ulcers in animals.
- Some laboratory studies also suggest that EDTA chelation may prevent collection of platelets ([or plaque] which can otherwise lead to formation of blood clots and prevent blood flow) on the walls of blood vessels [such as arteries]. These ideas are theoretical, however. [3]
In laboratory science, EDTA is also used for:
- Scavenging metal ions: in biochemistry and molecular biology, ion depletion is commonly used to inactivate metal-dependent enzymes which could damage DNA or proteins
- Complexometric titrations.
- Buffer solutions.
- Determination of water hardness.
- EDTA may be used as a masking agent to remove a metal ion which would interfere with the analysis of a second metal ion present
- An anticoagulant in medical and laboratory equipment.
- A preservative (usually to enhance the action of another preservative such as benzalkonium or thiomersal) in ocular preparations and eyedrops. See "les conservateurs en opthalmologie" Doctors Patrice Vo Tan & Yves lachkar, Librarie Médicale Théa.
- A titrant used to determine nickel concentration in an electroless nickel plating bath.
- In metallography to remove staining due to etchants. Metal oxides are removed by gently swabbing with EDTA and rinsing in water.

What is the difference between disodium edetate and EDTA?
EDTA is in full name writing: 'Ethylenediaminetetraacetic acid', a tetraprotic (H+) acid.It's IUPAC name is 2,2',2'',2'''-(Ethane-1,2-diyldinitrilo)-tetra-acetic acidShorthanded: H4EDT-acetate, or H4EdetateSo consequently disodium edetate is Na2H2EDT-acetate, or Na2H2Edetate, thus a 'better' name would be disodium dihydrogen edetate
Write down the reaction equation of Zn2 plus and EDTA?
The reaction equation between Zn^2+ and EDTA is: Zn^2+ + EDTA → Zn(EDTA)^2-
What is tertrasodium edta?
Tertrasodium EDTA is a chelating and preservative agent.
How many grams of EDTA do you add to make a 3.7 percent EDTA solution?
To make a 3.7% EDTA solution, you would add 3.7 grams of EDTA to 100 mL of solution.
What is colour of EDTA metal complex?
what is colour of Mg2plus- EDTA complex?
What is the inversion for a edta tube?
After collection, a EDTA tube should be inverted several times gently to ensure thorough mixing of the blood with the anticoagulant. This helps prevent clotting and ensures proper preservation of the sample for analysis.
Why do you use Fe-EDTA in murashige and skoog medium?
Fe-EDTA is used in Murashige and Skoog medium as a source of iron for plant tissue culture. Iron is an essential micronutrient required for proper plant growth and development. Fe-EDTA provides a stable form of iron that is readily available to plants in the medium.

When edta is insoluble in distilled water then how to make 0.01N edta solution?
use heat to heat the solution and add EDTA slowly to dissolve it.
What does it mean when blood test shows that EDTA has clotted?
If a blood test shows that EDTA has clotted, it may indicate improper handling of the blood sample, which could lead to inaccurate test results. EDTA is an anticoagulant commonly used to prevent blood from clotting during sample collection. It is important to ensure proper techniques are used to collect and handle blood samples to avoid this issue.
Why EDTA is not dissolved in water?
EDTA is sparingly soluble in water because it forms complexes with metal ions, reducing its solubility. The formation of strong metal-EDTA complexes makes it challenging for EDTA to dissolve in water because it ties up with metal ions in solution.
What is the proper order of draw for a syringe method?
The proper order of draw for a syringe method is: Blood culture tubes Coagulation tubes Serum tubes Heparin tubes EDTA tubes Glycolysis inhibitor tubes
Why is disodium salt of EDTA preferred to EDTA?
The disodium salt of EDTA is preferred over EDTA because it is more soluble in water, which makes it easier to handle and use in aqueous solutions. Additionally, the disodium salt has a higher stability in a wider range of pH levels compared to EDTA alone, making it more versatile for various applications.
