Physical Properties

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/
Density
1.8 to 2.5 at 77 °F (USCG, 1999) approx 1.7 g/cu cm Density 1.679, loses 5H2O at 48 °C /Disodium phosphate heptahydrate/ MP 35 °C, density 1.5235, readily loses 12H2O at 100 °C /Disodium phosphate dodecahydrate/ 0.5-1.2 g/cm³
Physical Description
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. Pellets or Large Crystals; Liquid; Dry Powder; Other Solid Anhydrous disodium hydrogen phosphate is a white, hygroscopic, odourless powder. Hydrated forms available include the dihydrate: a white crystalline, odourless solid; the heptahydrate: white, odourless, efflorescent crystals or granular powder; and the dodecahydrate: white, efflorescent, odourless powder or crystals Colorless or white hygroscopic solid; [Hawley] White powder; WHITE OR COLOURLESS HYGROSCOPIC CRYSTALS OR POWDER.
