EDTA-ACID
EDTA acid (ethylenediamine tetraacetic acid, Ethylenediaminetetraacetic acid) is a commonly used chelating agent, its physical paper as follows:
Molecular formula: C₁₀H₁₆N₂O₈
Molecular weight: 292.24 g/mol
Appearance:Pure EDTA acid is usually a white crystalline powder.
Solubility in water: slightly dissolved, solubility at 20°C is about 0.5 g/L.
Solubility in acid and alkali solutions is better, especially in alkaline solutions solubility is significantly improved.
Insoluble in organic solvents such as ethanol and ether.
Melting point: approximately 240°C (decomposition).
Stable at room temperature and pressure, but sensitive to moisture, easy to absorb moisture.
It is relatively stable to light and heat, but may decompose into harmful gases such as carbon monoxide, carbon dioxide and nitrogen oxides at high temperatures.
The pH of its aqueous solution is acidic, but the specific value depends on the solubility and concentration.
Density: Approximately 0.86 g/cm³ (20°C).

Ethylenediamine tetraacetic acid (EDTA) is an important chelating agent, which can form stable water-soluble complexes with various metal ions. This characteristic makes it have wide application value in many fields.In agriculture, it is widely used in the preparation of trace element fertilizers. By chelating technology, it can improve the solubility and absorption rate of trace elements, and promote the growth and development of plants. In addition, it can be used to improve the soil environment and help plants absorb nutrients better.In addition, it is used in the preparation of certain drug formulations to improve the stability and bioavailability of drugs.In the cosmetics industry, it is added to various skin care products and shampoos as a chelating agent to chelate metal ions in water and prevent these metal ions from adverse reactions with other ingredients in the product, thereby extending the shelf life of the product and maintaining its efficacy.
