iav yog xim los ntawm ntxiv cov hlau oxides lossis hmoov hlau rau molten iavNyob ntawm cov hlau, lub khob yuav siv xim tshwj xeeb. Tej zaum koj yuav tau pom "cob alt xiav" iav - yog, xim ntawd los ntawm kev ntxiv cob alt. Copper oxides kuj ua iav xiav rau ntsuab ntsuab.
Yuav ua li cas xim daim iav ua?
iav yog tsim los ntawm kev sib xyaw ua ke ntawm qee hom silica xws li xuab zeb, alkali xws li potash los yog dej qab zib, thiab txiv qaub lossis txhuas oxide. Cov xim yog tsim los ntawm ntxiv cov hlau oxide rau cov khoom siv rawtooj liab oxide, nyob rau hauv cov xwm txheej sib txawv, ua rau ruby, xiav, lossis ntsuab xim hauv iav.
Yuav siv tau dab tsi rau xim iav?
Ntau cov ntaub ntawv feem ntau yog siv rau xim iav, suav nrog cob alt (yog li lub npe!), txhuas, uranium, tooj liab thiab txawm kub. Xim yog qhov koj pom thawj zaug txog iav, thiab nws feem ntau yog ib qho ntawm nws cov ntsiab lus zoo nkauj tshaj plaws.
iav xiav hu li cas?
cob alt iav-paub tias "sm alt" thaum av ua cov xim-yog cov iav sib sib zog nqus xiav uas npaj los ntawm suav nrog cob alt compound, feem ntau cob alt oxide lossis cob alt carbonate, hauv ib khob yaj. Cob alt yog cov tshuaj pleev xim tawv heev thiab yuav tsum muaj tsawg heev kom pom cov xim xim.
Puas iav liab muaj kub hauv nws?
Nws tau pom kom muaj feeb ntawm kub … Lawv piav txog kev siv manganese thiab tooj liab los ua liab, thiab ib daim ntawv qhia txog kev siv kub. Liab iav ua los ntawm kub tsis yog ib qho yooj yim txheej txheem. Cov kub yuav tsum tau ua rau hauv ib lub colloid los ntawm dissolving kub nyob rau hauv ib tug daws ntawm nitric acid thiab hydrochloric acid (aqua regia).
