Physical and Chemical Properties
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 (14 g/100 mL at 20°C, 30 g/100 mL at 60°C)
Other Solvent: Insoluble in organic solvents (e.g., ethanol)
Aqueous Solution pH: 9.5-10.5 (1% solution)
Decomposition Temperature: 622°C (into sodium pyrophosphate and sodium metaphosphate)
Hydrate Stability: Hexahydrate tends to effloresce in dry air
Hygroscopicity: Strong; easily absorbs moisture from the air
Chelating Ability: Forms stable soluble complexes with metal ions (calcium, magnesium, iron)
