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. |
