Khoom
Sodium acid pyrophosphate | 7758-16-9 | Sapp zaub mov muaj additive
Khoom Piav Qhia
(1) cov hmoov dawb ntawm granular, txheeb ze ntom 1.86g / m. Soluble hauv dej thiab insoluble hauv ethanol. Yog tias nws cov kua aqueous yog rhuab ua ke nrog diluted inorganic acid, nws yuav muaj hydrolyzed rau hauv phosphoric acid.
(2) xim rau cov sodium acid pyrophosphate yog hydroscopic, thiab thaum nqus dej noo nws yuav dhau los ua cov khoom lag luam nrog hexahydates. Yog tias nws yog rhuab ntawm qhov kub tshaj 220 ℃., Nws yuav decomposed rau sodium meta phosphate.
