Physicochemical property
| Molecular weight: 367.86 g/mol | Appearance: white crystalline or powdery solid. |
| Odor: Odorless or slightly sulphide odor. | Density: 2.52 g/cm³ (25°C). |
| Melting point: about 622°C (decomposition). | Chemical Safety: Unrestricted goods |
| Solubility: Water: easily soluble in water, the aqueous solution is weakly alkaline (pH about 9-10); Organic solvent: insoluble in ethanol, and other organic solvents. |
| Hydrolysis reaction: It is gradually hydrolyzed in water to form orthophosphate |
| Complexation: Form a soluble complex with metal ions (e.g. Ca² +, Mg² +) for softening hard water. |
| Thermal stability: When heated to high temperatures (>600°C) it decomposes to form sodium phosphate and oxygen. |
| Acid base: The aqueous solution is weakly basic and can react with acid to form phosphate. |
