Sodium dihydrogen phosphate, also known as acid sodium phosphate, has a molecular formula of NaH2PO4·2H2O and NaH2PO4, the relative molecular masses are 156.01 and 119.98. Anhydrous and dihydrate, dihydrates are colorless to white crystalline or crystalline powders, and anhydrides are white powders or granules. Soluble in water, almost insoluble in ethanol. 100 °C lose crystal water and continue heating, it will produce acid sodium pyrophosphate. Colorless crystal or white crystalline powder. Odorless, salty, sour. The heat loses all the water of crystallization at 100°C, and it turns into sodium metaphosphate. Soluble in water, almost insoluble in ethanol, its aqueous solution is acidic. The 0.1 mol/L aqueous solution had a pH of 4.5 at 25C. Relative density 1.915. Melting point 60°C. The commodity also has a molecule of crystal water.
