Similarities and differences of Disodium salt and Tetranodium salt.
EDTA (EDTA, ethylenediaminetetraacetic acid) is an aminopolycarboxylic acid, which is a solid substance (crystalline powder) that is perfectly soluble in water and alkalis, but practically insoluble in alcohol and has a white color.
This product is most in demand for the contact of calcium and iron ions. This acid binds such ions as a chelating hexadentate agent. EDTA has an excellent ability to interact with metals.
Disodium salt (another name is Trilon B) is an aminopolycarboxylic acid synthesized as a by—product in the manufacture of an acid and a compound that consists of two sodium cations associated with forms of disodium aminopolycarboxylic acid.
Tetranatrium salt is an aminopolycarboxylic acid synthesized as a by—product in the manufacture of an acid and a compound that consists of four sodium ions associated with forms of tetranatrium aminopolycarboxylic acid.

Similarities and differences of products
Tetranatrium salt is an aminopolycarboxylic acid synthesized as a by—product in the manufacture of an acid and a compound that consists of four sodium ions associated with forms of tetranatrium aminopolycarboxylic acid.
Disodium salt is used in food with a neutral and acidic environment: for example, liquid soap, laundry rinses, hair shampoos, skin tonics, lotions, creams. Tetranatrium salt is used in alkaline foods: for example, in the manufacture of personal hygiene products. Also, both acids are in demand in the production of rubbers and polymers, oil production (used for cleaning wells on oil platforms), fuel gas purification (the product is launched in a circle, and the partial flow is burned, which makes it possible to eliminate emissions into wastewater).
As for the differences between trilon B and tetranatrium salt, there are several of them.
• The formula of disodium is - C10H14N2Na2O8; tetranatria — C10H14N2Na4O8.
• Disodium — two sodium cations, tetranatrium — four sodium ions.
• The hydrogen index of disodium salt is below seven — from four to six. The hydrogen index of the tetranatrium salt is higher than seven — from ten to eleven.
• All 4 negatively charged oxygen atoms in the disodium salt are bound to only 2 sodium atoms, and 4 negatively charged oxygen atoms in the tetranodium salt are bound to 4 sodium atoms.
It is important to know that EDTA requires special handling and storage. So, the container in which the products are stored must be tightly closed. The room should be cool, and it is also important that direct rays of the sun do not fall. Do not allow the formation of dust (it is dangerous to inhale it), contact with clothing, skin and mucous membranes. While working with such salts, it is necessary to worry about high-quality ventilation, and after work it is necessary to wash your hands thoroughly. Salt should not be allowed to come into close contact with beverages, food and other similar goods.
