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)
