Puas yog barium carbonate yog dawb precipitate?
Barium carbonate yog dawb precipitate, barium carbonate, nrog ib tug molecular mis ntawm BaCO3 thiab molecular hnyav ntawm 197.34.Nws yog ib qho inorganic compound thiab dawb hmoov.Nws yog qhov nyuaj rau yaj hauv dej thiab yooj yim soluble hauv cov kua qaub.Nws yog tshuaj lom thiab muaj ntau yam kev siv.Nws yog me ntsis soluble hauv dej uas muaj carbon dioxide.Nws kuj yog soluble hauv ammonium chloride los yog ammonium nitrate tov los tsim ib qho nyuaj, thiab yog soluble hauv hydrochloric acid thiab nitric acid kom tso carbon dioxide.
Barium carbonate yog cov hmoov dawb hnyav, soluble hauv dilute hydrochloric acid, dilute nitric acid, acetic acid, ammonium chloride tov thiab ammonium nitrate tov, me ntsis soluble hauv dej uas muaj carbon dioxide, yuav luag insoluble hauv dej, insoluble hauv cawv, decomposes thaum raug. acid, thiab qhov kev txiav txim ntawm sulfuric acid tsim dawb barium sulfate precipitate, uas decomposes rau hauv barium oxide thiab carbon dioxide ntawm txog 1300 ° C.Tus txheeb ze ceev yog 4.43, tsis tshua muaj toxicity, thiab me ntsis hygroscopic.
