Sodium phosphate monobasic CAS 7558-80-7
Sodium phosphate monobasic bụ kristal na-enweghị ụcha ma ọ bụ ntụ ntụ kristal na-acha ọcha, na-esighị ike na nke na-adị ngwa ngwa na mmiri. Ngwọta mmiri ya bụ acidic na ọ fọrọ nke nta ka ọ ghara ịsacha ya na ethanol. Mgbe ọ na-ekpo ọkụ, ọ na-efunahụ mmiri kristal ya wee ghọọ acidic sodium pyrophosphate (Na3H2P2O7). A na-ejikarị eme ihe na ụlọ ọrụ ịgba ụka iji mezie acidity na alkalinity, a na-ejikarị ya na disodium hydrogen phosphate eme ihe dị ka ihe na-eme ka nri dị mma na nhazi nri. Dị ka ịkwalite nkwụsi ike ọkụ nke ngwaahịa mmiri ara ehi, ime pH regulators na binders maka ngwaahịa azụ, wdg.
