Physicochemical property
| Molecular weight: 163.94 g/mol | Appearance: white crystalline or powdery solid. |
| Odor: Odorless or slightly sulphide odor. | Density: 1.62 g/cm³ (dodecahydrate, 20°C). |
| Melting point: approx. 73.4°C (dodecahydrate decomposition). | Chemical Safety: Unrestricted goods |
|
Solubility: Water: easily soluble in water, aqueous solution is strongly alkaline (pH about 12); Organic solvent: insoluble in ethanol, and other organic solvents. Hydrolysis reaction: Fully ionized in water to form phosphate ions and sodium ions Complexation: Form an insoluble precipitate with metal ions (e.g. Ca² +, Mg² +) for softening hard water. Thermal stability: It decomposes when heated to high temperatures, forming sodium phosphate and oxygen. Acid base: The aqueous solution is strongly basic and can react with acid to form phosphate |

Potassium dihydrogen phosphate (KH₂PO₄) is an important chemical product that is widely used in agriculture, , medicine, and industry. In recent years, with the acceleration of the global agricultural modernization process and the promotion of environmental protection policies, the potassium dihydrogen phosphate market has shown a rapid development trend.
Corrosion inhibitor
Potassium dihydrogen phosphate can be added as a corrosion inhibitor to water treatment systems, especially in boiler water and cooling water systems. It can form stable complexes with calcium and magnesium ions in water to reduce the formation of scale, thus protecting equipment from corrosion.
pH regulator
Potassium dihydrogen phosphate has a certain buffering capacity and can be used to regulate the pH value of the water body to keep it in a suitable range (usually 6.5-8.5), thus optimizing the water treatment effect.
Nutrient source
In sewage treatment (such as biological treatment process), potassium dihydrogen phosphate can be used as a phosphorus source to provide essential nutrients for microorganisms, promote the growth and metabolism of microorganisms, and improve the efficiency of sewage treatment.
