Disodium EDTA, also known as edta-2na, is a good coordination agent in chemistry. The chemical formula is c10h14n2na2o8 with molecular weight of 336.206. It has six coordination atoms. The complex formed is called chelate. EDTA is often used in coordination titration, which is generally used to determine the content of metal ions. The appearance of disodium EDTA is white or milky crystalline powder, odorless and water-soluble, but it will not dissolve in ethanol and ether.

Disodium EDTA is a very important chelating agent in industry. It can act on heavy metal antidotes, complexing agents, antioxidant synergists, stabilizers, softeners and other metal reagents. Disodium EDTA is also an important complexing agent for complexing metal ions and separating metals. Daily cleaning.

In addition to being widely used in industry, disodium EDTA also has many applications in other fields. This is because disodium EDTA has some special advantages

1. EDTA has a wide range of coordination properties and can form stable chelates with almost all metal ions.

Advantages: it provides the possibility of extensive determination of elements (better than acid-base and precipitation methods).

Disadvantages: easy interference between multiple components - selectivity.

2. The coordination ratio between EDTA and m-edta is mostly 1:1.

3. Most of the chelates are charged, so they can be dissolved in water and react quickly.

To sum up, disodium EDTA is mainly used for complexing metal ions to produce complex ions. Because it has strong ability to absorb metal ions, it is strictly prohibited to be used in organisms. Otherwise, the dissociation of metal ions in proteins will directly cause the death of life. In addition to being widely used in industry, it is also a blood anticoagulant. Disodium EDTA can combine with calcium ions in the blood to form a chelate, so as to prevent blood coagulation.
