Properties
Anhydrous sodium pyrophosphate is a kind of white crystalline powder, which is easy to absorb water and deliquescence in air; decahydrate sodium pyrophosphate is a kind of colorless monoclinic crystal or white crystal or crystalline powder, which is easy to weathering in dry air. Crystal water is lost when heated to 100 ° C. It is soluble in water, alkaline in water and insoluble in alcohol. The aqueous solution is stable below 70 ° C and hydrolyzes to disodium hydrogen phosphate when boiling. It has strong pH buffering property and chelating effect on metal ions.
Packaging
