Inner Mongolia disodium hydrogen phosphate lowest price

Lose all crystal disodium hydrogen phosphate easily weathered in the air, at room temperature when placed in the air to form water was lost about seven five crystal water, heated to 100 ℃, water from Anhydrous, 250 ℃ decomposition into focus sodium. Efflorescent in air, easily lose five crystal water molecules to form a seven water was (Na2HPO4.7H2O). Soluble in water, insoluble in alcohol. The reaction solution was slightly alkaline (PH 0.1-1N solution was about 9.0). Loss of crystal water from Anhydrous at 100 ℃, at 250 ℃ decomposed into sodium pyrophosphate. PH 1% aqueous solution is 8.8 to 9.2; insoluble in alcohol. Melted and lost five crystal water at 35.1 ℃.
