Sodium pyrophosphate CAS 7758-16-9 yog dab tsi?

Disodium dihydrogen pyrophosphate yog flammable nyob rau hauv lub xub ntiag ntawm H pore tus neeg saib xyuas, thiab yuav emission lom phosphorus oxide fumes thaum rhuab. Disodium dihydrogen pyrophosphate zoo nkaus li ib qho dawb monoclinic crystalline hmoov los yog cov khoom molten. Tus txheeb ze ntom ntom yog 1.86. Soluble hauv dej, insoluble hauv ethanol. Cov tshuaj aqueous yog hydrolyzed rau phosphoric acid los ntawm cua sov nrog dilute inorganic acid.
