Measured properties

Appearance: Sodium phosphate, dibasic appears as a colorless to white crystalline solid. Soluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit spread to the environment. Used as a fertilizer, in pharmaceuticals, in food processing, and for many other uses. · Liquid, Dry Powder, Other Solid, CBI
Odour: NONE
Melting point: MP: loses H2O at 92.5 °C, Specific gravity: 2.066 at 15 °C /Disodium phosphate dihydrate/ · Translucent crystals or granules, readily loses 5 mols of water on exposure to air at ordinary temp. Melting point 34-35 °C (when it contains the full 12 mols of H2O). Specific gravity 1.5. Soluble in 3 parts water, practically insoluble in alcohol. Aqueous solution is alkaline, pH=9.5. /Dodecahydrate/
Solubility: greater than or equal to 100 mg/mL at 68 °F (NTP, 1992) · Freely soluble in water. Insoluble in ethanol
Density: 1.8 to 2.5 at 77 °F (USCG, 1999) · approx 1.7 g/cu cm
Stability: On exposure to air, it absorbs 2-7 moles water depending on humidity and temperature. · Stable in air. /Disodium Phosphate Heptahydrate/
pH: Between 8,4 and 9,6 (1 % solution) · pH = 9.1 for 1% aq soln at 25 °C
Dissociation constant: pKa1 = 2.15, pKa2 = 6.83, pKa3 = 12.38 (phosphoric acid), all at 25 °C
