Qhov sib txawv tseem ceeb ntawm nruab nrab thiab amphoteric oxides yog qhov nruab nrab oxides tsis muaj acidic los yog qhov tseem ceeb, whereas amphoteric oxides muaj ob qho tib si acidic thiab yooj yim zog.
Ib oxide yog ib qho binary compound uas muaj cov tshuaj lom neeg ua ke nrog ib lossis ntau dua oxygen atoms. Txij li cov pa oxygen yog qhov muaj zog heev, nws tuaj yeem tsim oxides nrog ob qho tib si hlau thiab nonmetals. Muaj 4 hom oxide loj xws li acidic oxides, yooj yim oxides, nruab nrab oxides, thiab amphoteric oxides, raws li lawv cov khoom thiab cov tshuaj tiv thaiv.
Neutral Oxides yog dab tsi?
Neutral oxides yog cov tshuaj sib txuas uas muaj cov tshuaj lom neeg sib txuas rau ib lossis ntau dua oxygen atoms thiab tsis muaj acidic lossis cov xwm txheej. Yog li ntawd, txij li thaum lawv tsis muaj acidic thiab yooj yim zog, lawv tsis tuaj yeem tsim cov ntsev thaum lawv hnov mob nrog cov kua qaub lossis cov hauv paus.
Daim duab 01: Cov pa roj carbon monoxide yog ib qho nruab nrab Oxide
Xav txog qee qhov piv txwv, nitrogen monoxide (NO), carbon monoxide (CO) thiab nitrous oxide (N2O) yog cov oxides nruab nrab.
Amphoteric Oxides yog dab tsi?
Amphoteric oxides yog cov tshuaj oxide uas muaj ob qho tib si acidic thiab cov xwm txheej. Yog li ntawd, lawv tuaj yeem hnov mob nrog ob qho tib si acids thiab cov hauv paus, tsim cov ntsev sib txuas thaum kawg. Ntxiv mus, thaum hnov mob nrog cov kua qaub, cov oxides qhia cov yam ntxwv yooj yim thiab rov ua dua. Txawm li cas los xij, ob qho tib si tshwm sim ua rau ntsev thiab dej. Qee qhov piv txwv muaj raws li hauv qab no:
Zinc oxide (ZnO) raws li cov kua qaub hauv cov tshuaj tiv thaiv nrog NaOH yooj yim compound;
ZnO + 2NaOH → Na2ZnO2 + H2O
Zinc oxide ua lub hauv paus hauv cov tshuaj tiv thaiv nrog HCl acidic compound;
ZnO + 2HCl → ZnCl2 + H2O
Daim duab 02: Zinc Oxide Powder
Aluminium oxide (Al2O3) as an acid in reaction with NaOH;
Al2O3 + 2NaOH → 2NaAlO2 + H 2O
Aluminium oxide (Al2O3) as a base in reaction with H2 SO4;
Al2O3+ 3H2SO4 → Al2(SO4)3 + 3H2 O
Qhov txawv ntawm qhov nruab nrab thiab Amphoteric Oxides yog dab tsi?
Oxides yog cov tshuaj sib xyaw uas muaj cov tshuaj lom neeg (hlau lossis nonmetal) sib txuas rau ib lossis ntau dua oxygen atoms. Nruab nrab thiab amphoteric oxides yog ob ntawm plaub hom oxide loj. Qhov sib txawv tseem ceeb ntawm nruab nrab thiab amphoteric oxides yog qhov nruab nrab oxides tsis muaj acidic lossis cov xwm txheej, hos amphoteric oxides muaj ob qho tib si acidic thiab cov yam ntxwv. Yog li, amphoteric oxides tuaj yeem tsim cov ntsev thiab dej thaum ua haujlwm nrog cov kua qaub lossis lub hauv paus, thaum cov oxides nruab nrab tsis tuaj yeem tsim cov ntsev thiab dej thaum ua rau cov kua qaub lossis cov hauv paus. Yog li, peb tuaj yeem xav txog qhov no yog qhov sib txawv ntxiv ntawm nruab nrab thiab amphoteric oxides, stemming los ntawm qhov sib txawv dhau los.
Summary – Neutral vs Amphoteric Oxides
Hauv cov ntsiab lus, oxides yog cov tshuaj lom neeg muaj tshuaj lom neeg (hlau lossis nonmetal) sib txuas rau ib lossis ntau dua oxygen atoms. Hais txog lawv cov khoom, qhov sib txawv tseem ceeb ntawm nruab nrab thiab amphoteric oxides yog qhov nruab nrab oxides tsis yog acidic los yog qhov tseem ceeb, whereas amphoteric oxides yog ob qho tib si acidic thiab yooj yim.
