Sodium dihydrogen phosphate, also known as acid sodium phosphate. The molecular formula is NaH2PO4·2H2O and NaH2PO4,The relative molecular mass is 156.01 and 119.98.Divided into anhydrous and dihydrate, dihydrate is colorless to white crystalline or crystalline powder, anhydrous is white powder or particles.Easily soluble in water, almost insoluble in ethanol. After losing the crystallization water at 100°C and continuing to heat, acid sodium pyrophosphate is generated.
Specification:HG/T2767-1996
