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. |

1.agriculture
Efficient water soluble fertilizer
Provide plants with essential phosphorus (P) and potassium (K), promote root development,
flowering and fruiting, and enhance stress resistance (such as drought and cold resistance).
Foliar spraying: quickly supplement nutrients, especially suitable for emergency treatment when the
fruit is expanding or nutrient-deficient.
Drip irrigation system: Water and fertilizer integration technology that is easily soluble in water
and suitable for modern precision agriculture.
Promote photosynthesis and quality improvement
Increase the sugar content of fruit, improve color and taste,
often used in cash crops (such as grapes, strawberries, tea).
Increase plant resistance to pests and diseases and reduce pesticide use.
Soil regulation
The pH value is close to neutral, suitable for a variety of soils to avoid acidification or salinization problems.
2.Industrial field
Buffer and pH regulator
Pharmaceutical industry: Used for pH stabilization in the production of pharmaceuticals,
such as injections or oral liquids.
Food industry: As a food additive (E340), regulate the acid-base balance of dairy products, beverages, etc.
Surface treatment and plating
Provide phosphorus source in metal plating solution to enhance corrosion resistance of coating.
Used in cleaning agent formulations to remove metal surface oxides.
Ceramic and glass manufacturing
As a flux, reduce the firing temperature, improve product transparency or strength.
3.laboratory and scientific research
Buffer solution preparation
Compound with dipotassium hydrogen phosphate (K₂HPO₄) to prepare buffers at
different pH values (e.g. pH 4.5-8.0 range) for biological experiments (e.g. PCR, enzyme reactions).
Analytical reagent
Used as a standard for phosphorus or potassium for spectral analysis or titration.
Microbial medium
Provides phosphorus and potassium for microbial growth, commonly found in bacterial or fungal cultures.
