Sodium phosphate monobasic CAS 7558-80-7
Sodium phosphate monobasic bụ ntụ ntụ kristal na-enweghị agba ma ọ bụ kristal ọcha, enweghị isi ma dịkwa mfe ịgbaze na mmiri. Mmiri mmiri ya na-adị ka acidic ma fọrọ nke nta ka ọ ghara ịgbaze na ethanol. Mgbe a na-ekpo ọkụ, ọ na-efunahụ mmiri kristal ya ma gbazee ghọọ sodium pyrophosphate acidic (Na3H2P2O7). A na-ejikarị ya eme ihe n'ụlọ ọrụ ịgbaze ihe iji chịkwaa acidity na alkalinity, a na-ejikarị ya na disodium hydrogen phosphate dị ka ihe na-eme ka mma nri dịkwuo mma na nhazi nri. Dịka imeziwanye nkwụsi ike okpomọkụ nke ngwaahịa mmiri ara ehi, ime pH regulators na ihe njikọ maka ngwaahịa azụ, wdg.
