EDTA-ACID
EDTA has multiple carboxylic acid groups (-COOH) and amino groups (-NH2), which can form stable hexagonal complexes with metal ions. The pH of the it solution can be adjusted by adding an acid or base. Common acids include hydrochloric acid (HCl), while common bases include sodium hydroxide (NaOH). it is a white crystalline powder, soluble in water to form a colorless solution. The solubility of it in water is affected by pH value, and the solubility is higher under alkaline conditions. When it is added to water, it gradually dissolves to form a transparent solution. If the pH of the solution is low, you can see the pH increase because the it will consume hydrogen ions. If insoluble metal salts precipitate in the solution, the precipitate may dissolve after the addition of it, because it forms soluble complexes with metal ions.

EDTA is an important complexing agent. it is widely used, can be used as color photosensitive material washing processing bleaching fixing solution, dyeing AIDS, fiber treatment AIDS, cosmetic additives, blood anticoagulant, detergent, stabilizer, synthetic rubber polymerization initiator, it is a representative of chelating agent. It can form stable water-soluble complexes with alkaline earth metals, rare earth elements and transition metals. In addition to sodium salts, there are ammonium salts and iron, magnesium, calcium, copper, manganese, zinc, cobalt, aluminum and other salts, which have different uses. In addition, it can also be used to make harmful radioactive metals quickly excreted from the body to play a detoxification role. It's also a water treatment agent. it is also an important indicator, but used to titrate metal nickel, copper, etc., when used with ammonia, in order to play the role of indicator.
