Qhov sib txawv tseem ceeb ntawm cob alt oxide thiab cob alt carbonate yog cob alt oxide zoo li cov hmoov dub, hos cob alt carbonate zoo li cov hmoov liab-violet.
Cob alt oxide thiab cob alt carbonate yog cov tshuaj inorganic. Ob lub tebchaw no muaj cov tshuaj lom neeg thiab lub cev sib txawv. Thaum xub thawj pom, lawv tshwm nyob rau hauv cov xim sib txawv, yog li peb tuaj yeem muab lub npe zoo li qhov txawv ntawm lawv.
Cob alt Oxide yog dab tsi
Cob alt (II) oxide los yog cob alt monoxide yog ib qho inorganic compound uas muaj cov tshuaj formula CoO. Nws tshwm raws li cov hmoov dub. Txawm li cas los xij, qee zaum peb tuaj yeem soj ntsuam nws li txiv ntseej ntsuab muaju lossis cov muaju liab thiab. Qhov sib xyaw no yog siv dav hauv kev lag luam ceramics ua ib qho ntxiv rau enamels. Nws tseem yog ib qho tseem ceeb hauv kev lag luam tshuaj rau kev tsim cov cob alt (II) ntsev.
Thaum xav txog cov qauv thiab cov khoom ntawm cob alt (II) oxide, nws feem ntau tau txais cov qauv periclase, uas zoo li cov qauv ntawm pob zeb ntsev. Thaum qhov kub thiab txias heev, cov tshuaj no yog antiferromagnetic. Tsis tas li ntawd, cov tshuaj no yog insoluble hauv dej. Nws tuaj yeem hnov mob nrog cov ntxhia acids los tsim cov ntsev sib xyaw.
Dhau li ntawd, muaj ntau txoj hauv kev los tsim cov cob alt (II) oxide. Piv txwv li, cob alt (II, III) oxide nyob rau hauv decomposition ntawm kub heev thiab cov ntaub ntawv cob alt (II) oxide. Rau kev tsim cov khoom lag luam muaj cob alt (II) oxide, peb tuaj yeem ua cov txheej txheem electrolysis siv cov tshuaj cob alt (II) chloride. Ntxiv rau qhov ntawd, peb tuaj yeem tsim cov cob alt (II) oxide los ntawm nag lossis daus ntawm hydroxide ua raws li thermal dehydration.
Daim duab 01: Cob alt (II) Oxide Structure
Ntxiv mus, muaj ntau daim ntawv thov ntawm cob alt (II) oxide. Nws yog ib qho tseem ceeb raws li ib tug colouring neeg sawv cev nyob rau hauv kiln-hluav taws xob pottery ntau lawm. Qhov no additive muab cov khoom nrog ib tug sib sib zog nqus xiav xim hu ua cob alt xiav. Yog li ntawd, nws kuj yog siv nyob rau hauv zus tau tej cov cob alt xiav iav.
Cob alt Carbonate yog dab tsi?
Cob alt carbonate lossis cob alt (II) carbonate yog ib qho inorganic compound uas muaj cov tshuaj formula CoCO3. Nws yog xim liab-violet hmoov uas zoo li cov xim ntawm permanganate. Peb tuaj yeem npaj qhov sib xyaw no los ntawm kev sib xyaw cov ntsiab lus ntawm cob alt (II) sulfate thiab sodium bicarbonate. Cob alt carbonate muaj cov qauv ntawm calcite qhov twg cob alt atoms nyob rau hauv octahedral coordination geometry.
Daim duab 02: Pom ntawm Cob alt Carbonate
Ntxiv mus, qhov sib xyaw no koom nrog cov tshuaj lom neeg sib txawv vim muaj cov carbonate anion. Cov cua kub no carbonate muab cov khoom oxide ib nrab nrog rau cov pa roj carbon dioxide. Lub resultant ib nrab oxidized compound ces reversibly converts rau hauv cob alt (II) oxide ntawm kub kub. Cov tshuaj no kuj tseem insoluble hauv dej. Tab sis nws tau nkag siab los ntawm cov ntxhia acids.
Muaj ntau daim ntawv thov ntawm cob alt carbonate. Nws yog lub hauv paus rau kev tsim cov cob alt carbonyl thiab ntau lwm cov ntsev cob alt. Nws kuj yog ib qho khoom siv hauv cov khoom noj khoom haus vim tias cob alt yog ib qho tseem ceeb. Ntxiv mus, nws yog ib qho precursor rau xiav pottery glaze.
Qhov txawv ntawm Cob alt Oxide thiab Cob alt Carbonate yog dab tsi?
Cob alt (II) oxide lossis cob alt monoxide yog cov khoom siv tsis muaj tshuaj lom neeg muaj cov tshuaj formula CoO thaum Cob alt carbonate los yog cob alt (II) carbonate yog ib qho inorganic compound muaj cov tshuaj formula CoCO3. Qhov sib txawv tseem ceeb ntawm cob alt oxide thiab cob alt carbonate yog cob alt oxide zoo li cov hmoov dub, hos cob alt carbonate zoo li cov hmoov liab-violet.
Hauv qab infographic teev ntau qhov sib txawv ntawm cob alt oxide thiab cob alt carbonate.
Summary – Cob alt Oxide vs Cob alt Carbonate
Cob alt oxide lossis cob alt (II) oxide thiab cob alt (II) carbonate muaj cob alt hlau ion muaj +2 oxidation xeev. Qhov sib txawv tseem ceeb ntawm cob alt oxide thiab cob alt carbonate yog cob alt oxide zoo li cov hmoov dub, hos cob alt carbonate zoo li cov hmoov liab-violet.
