  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 increasng with temperature.

At 20°C, solubility is approximately 14 g/100 mL.

At 60°C, solubility is approximately 30 g/100 mL.

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) into sodium pyrophosphate (Na₄P₂O₇) and sodium metaphosphate (NaPO₃).
Hydrate Stability The hexahydrate tends to effloresce in dry air, losing its water of crystallization.
Property Strong hygroscopicity; easily absorbs moisture from the air and may form clumps.
Property STPP has strong chelating ability, forming stable soluble complexes with metal ions such as calcium, magnesium, and iron in water.
Application This property makes it highly valuable in water treatment, detergents, and food processing.
