Sodium phosphate monobasic CAS 7558-80-7
Sodium phosphate monobasic yog ib qho tsis muaj xim crystalline lossis dawb crystalline hmoov, tsis muaj ntxhiab thiab yooj yim soluble hauv dej. Nws cov kua aqueous yog acidic thiab yuav luag insoluble hauv ethanol. Thaum cua sov, nws poob nws cov dej crystalline thiab decomposes rau hauv acidic sodium pyrophosphate (Na3H2P2O7). Feem ntau siv rau hauv kev lag luam fermentation los tswj acidity thiab alkalinity, nws feem ntau siv ua ke nrog disodium hydrogen phosphate ua cov khoom noj khoom haus zoo dua hauv kev ua zaub mov. Xws li kev txhim kho qhov ruaj khov thermal ntawm cov khoom noj mis nyuj, ua pH regulators thiab binders rau cov khoom ntses, thiab lwm yam.
