Sodium Dihydrogen Phosphate | 7558-80-7
Khoom Description
Product Description: Sodium dihydrogen phosphate yog cov xim tsis muaj xim lossis dawb crystalline hmoov, tsis muaj ntxhiab, yooj yim soluble hauv dej, nws cov kua aqueous yog acidic, yuav luag insoluble hauv ethanol, cua sov poob ntawm cov dej siv lead ua tuaj yeem decomposed rau hauv acid sodium pyrophosphate (Na3H2P2O7). Nws yog feem ntau siv hauv kev lag luam fermentation los kho pH, thiab nws feem ntau siv rau hauv kev ua zaub mov nrog disodium hydrogen phosphate ua zaub mov zoo.
Daim ntawv thov: Organic Intermediates thiab chiv
Cia:Cov khoom yuav tsum tau muab cia rau hauv qhov chaw ntxoov ntxoo thiab txias. Tsis txhob cia nws raug tshav ntuj. Kev ua tau zoo yuav tsis cuam tshuam nrog damp.
Standards ua:International Standard.
