| Molecular weight | 163.94 g/mol |
| Appearance | White crystalline or powdery solid |
| Odor | Odorless or slightly sulphide odor |
| Density | 1.62 g/cm³ (dodecahydrate, 20°C) |
| Melting point | approx. 73.4°C (dodecahydrate decomposition) |
| Chemical Safety | Unrestricted goods |
| Solubility | Water: easily soluble in water, aqueous solution is strongly alkaline (pH about 12); Organic solvent: insoluble in ethanol, and other organic solvents |
| Hydrolysis reaction | Fully ionized in water to form phosphate ions and sodium ions |
| Complexation | Form an insoluble precipitate with metal ions (e.g. Ca² +, Mg² +) for softening hard water |
| Thermal stability | It decomposes when heated to high temperatures, forming sodium phosphate and oxygen |
| Acid base | The aqueous solution is strongly basic and can react with acid to form phosphate |
