Khoom:
Sodium bisulfate (cov tshuaj formula:NAS 4), tseem hu ua acid sodium sulfate.Nws cov tshuaj anhydrous yog hygroscopic.Cov tshuaj aqueous yog acidic, thiab pH ntawm 0.1mol / L sodium bisulfate tov yog hais txog 1.4.Sodium bisulfate tuaj yeem tau txais ob txoj hauv kev.Los ntawm kev sib xyaw sodium hydroxide thiab sulfuric acid hauv cov nyiaj no, sodium bisulfate thiab dej tuaj yeem tau txais.NaOH + H2SO4 →NAS 4+ H2O Sodium chloride (lub rooj ntsev) thiab sulfuric acid tuaj yeem hnov mob ntawm qhov kub thiab txias los tsim sodium bisulfate thiab hydrogen chloride gas.NaCl + H2SO4 → NaHSO4 + HCl tsev ntxhua khaub ncaws (45% tov);extraction ntawm metallic nyiaj;txo cov alkalinity ntawm lub pas dej da dej;tsiaj noj;4 raws li kev khaws cia thaum soj ntsuam cov av thiab cov qauv dej hauv chav kuaj;Siv nyob rau hauv kev npaj ntawm sulfuric acid.
Daim ntawv thov
Raws li PH kho tus neeg sawv cev.Nws tuaj yeem ua rau ceramic.Nws kuj tuaj yeem siv los ua tus neeg sawv cev rau dyeing, hnyav rau melting ntxhia, tshuaj tua kab mob thiab tshuaj ntxuav tes rau hauv kev lag luam tshuaj txhua hnub, cov khoom siv raw rau sulfate ntsev thiab sodium alum, thiab tseem siv tau los ua roj av artesian. zoo thiab ameliorant.
