Details
English name: sodium phosphate
Alias: Trisodium phosphate anhydrous for food
Molecular formula: Na3PO4·nH2O (n=0,n=1,n=12)
Property: The important two are sodium phosphate tribasic dodecahydrate and anhydrous substance. Anhydrous substance is white crystal. Density 2.536g/cm3. Melting point 1340℃. Sodium phosphate tribasic dodecahydrate is colorless cubic crystal or white powder. Density 1.62g/cm3. Melting point 73.3℃. Decompose at 76.7℃. Turns into anhydrous substance after heating to 100℃ after losing 12 crystal water. Weathering in the dry air. Easily soluble in water. Its aqueous solution is strong alkaline. Insoluble in carbon disulfide and ethanol.
