Description
Name: Sodium Pyrophosphate
Molecular formula: Na4P2O7
Molecular weight: 265.9
Physical and Chemical property: White powder or crystal. Relative density is 2.534, melting point is 880OC, and boiling point is 938OC. Soluble in water, and the solubility in 100g water is 6.23 at the 20O C. The aqueous is alkaline and insoluble in alcohol. The aqueous is stable under 70OC, and after boiling, it hydrolyzes and becomes disodium hydrogen phosphate. Weathering in dry air and loss crystal water at 100OC. Easily absorb water in wet air. Combine with metal ion become complex. Meet with AG+ and become white silver pyrophosphate.
Executive standard: GB25557-2010
