Potassium dihydrogen phosphate (tshuaj formula: KH2PO4) yog khaws cia rau hauv lub thawv kaw thiab ruaj khov hauv huab cua. Nws poob dej ntawm 400 degree thiab ua pyrophosphate. Nws yog siv los npaj cov kev daws teeb meem tsis zoo, txiav txim siab arsenic, antimony, phosphorus, aluminium, thiab hlau, npaj phosphorus standard solutions, npaj kab lis kev cai media, thiab ntsuas inorganic phosphorus thiab alkaline phosphatase kev ua hauv cov ntshav.
Lub cev thiab tshuaj muaj zog:
Potassium dihydrogen phosphate yog xim tsis muaj xim tetragonal siv lead ua los yog dawb crystalline hmoov. Tus txheeb ze ntom ntom yog 2.338. Melting point 252.6 degree. Yooj yim rau yaj hauv dej, nrog solubility ntawm 83.5g / 100ml dej ntawm 90 degree. Cov tshuaj aqueous yog acidic, thiab pH tus nqi ntawm 1% potassium dihydrogen phosphate tov yog 4.6. Insoluble hauv cawv. Nws muaj deliquescence. Thaum rhuab mus rau 400 degree, nws melts mus rau hauv lub pob tshab kua thiab solidifies rau hauv opaque glassy potassium metaphosphate tom qab txias.
