Physicochemical Properties
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

Applications
1. Agriculture
  • Efficient water soluble fertilizer providing essential phosphorus (P) and potassium (K)
  • Promotes root development, flowering and fruiting, and enhances stress resistance (drought and cold resistance)
  • Foliar spraying quickly supplements nutrients, especially during fruit expansion or nutrient deficiency
  • Ideal for drip irrigation systems and water-fertilizer integration technology
  • Enhances photosynthesis, increases fruit sugar content, and improves color and taste
  • Boosts plant resistance to pests and diseases, reducing pesticide use
  • Neutral pH makes it suitable for various soils without causing acidification or salinization
2. Industrial Applications
  • Buffer and pH regulator: Used in pharmaceutical production (injections, oral liquids) and food industry (E340 additive for dairy products, beverages)
  • Surface treatment and plating: Provides phosphorus source in metal plating solutions to enhance corrosion resistance; used in cleaning agents to remove metal surface oxides
  • Ceramic and glass manufacturing: Acts as flux to reduce firing temperature and improve product transparency or strength
3. Laboratory and Scientific Research
  • Buffer solution preparation: Combined with dipotassium hydrogen phosphate (K₂HPO₄) to prepare buffers (pH 4.5-8.0 range) for biological experiments (PCR, enzyme reactions)
  • Analytical reagent: Serves as standard for phosphorus or potassium in spectral analysis or titration
  • Microbial medium: Provides essential phosphorus and potassium for bacterial or fungal cultures
