Physical and Chemical Properties of Sodium Tripolyphosphate
- Chemical Formula: Na₅P₃O₁₀
- Molecular Weight: 367.86 g/mol
- Appearance: White crystalline or powdery solid
- Form: Typically exists as an anhydrous compound (Na₅P₃O₁₀) or a hexahydrate (Na₅P₃O₁₀*6H₂O)
- Water Solubility: Highly soluble in water, with solubility increasing with temperature
- Other Solvent: Insoluble in organic solvents (e.g., ethanol)
- Aqueous Solution pH: The pH of a 1% aqueous solution is approximately 9.5-10.5, making it alkaline
- Decomposition Temperature: Decomposes at high temperatures (around 622°C)
- Hydrate Stability: The hexahydrate tends to effloresce in dry air
- Property: Strong hygroscopicity; easily absorbs moisture from the air
- Property: STPP has strong chelating ability with metal ions
- Application: Highly valuable in water treatment, detergents, and food processing
