Bismuth oxide suav tias yog ib yooj yim oxide , uas piav qhia txog qhov kev ua haujlwm siab nrog CO2. Txawm li cas los xij, thaum acidic cations xws li Si(IV) yog qhia nyob rau hauv cov qauv ntawm cov bismuth oxide , cov tshuaj tiv thaiv nrog CO2 tsis tshwm sim.
Hauv qhov no, bismuth oxide siv rau dab tsi?
Daim ntawv thov. Cov kev siv tseem ceeb ntawm bismuth oxide nanoparticles yog cov ntaub ntawv siv hluav taws xob, xws li hauv electrolyte lossis cathode ntawm cov khoom oxide roj hlwb (SOFC), nyob rau hauv bio-kev kho mob thiab mob qog noj ntshav thiab rau lwm yam photoconductive yam ntxwv nyob rau hauv nyias films.
Ib yam li ntawd, vim li cas bismuth tsis yog acidic? Bismuth oxide tsis yog acidic nyob rau hauv ib qho ntawm nws cov tshuaj tiv thaiv. Lub caij muaj tus nqi siab dua ntawm electronegativity yuav yog qhov tseem ceeb a tsis yog -hlau thaum uas tus nqi qis dua yuav yog hlau. Electronegativity txo qis ntawm kev txav ntawm sab saum toj mus rau hauv qab. thiab cov oxide ntawm Bi yog qhov yooj yim.
Tsis tas li ntawd, bismuth puas lom rau tib neeg?
Bismuth Toxicity yog suav tias yog ib qho tsawg kawg nkaus tshuaj lom cov hlau hnyav. Bismuth toxicity feem ntau yog txuam nrog raug rau bismuth ntsev (muag raws li lub npe Pepto-Bismol). Ua hauj lwm bismuth raug tsis tshua muaj. Bismuth tuaj yeem nqus tau, noj, lossis nqus los ntawm daim tawv nqaij.
Yuav ua li cas ua bismuth oxide?
Yog koj xav tau ua koj oxide , tsuas yaj lub bismuth nyob rau hauv nitric acid thiab thaum tag nrho cov hlau tau ploj lawm, ces boil rau cov kua. Ntawm ib qho taw tes koj tau ib daim ntawv ntub dej. Ua kom cua sov, tshem tawm cov dej vapor thiab vapor ntawm nitric acid. Ua kom cua sov ntxiv thiab muaj zog dua, koj tau nitric oxide (xim xim av).

Puas yog activated charcoal acidic lossis alkaline?
Tau ntau xyoo, activated charcoal tau siv rau kev kho mob thaum muaj xwm txheej ceev ntawm qee yam tshuaj lom. Nws cov khoom alkaline tso cai rau nws khi rau cov tshuaj lom thiab tiv thaiv lawv los ntawm kev nqus ntawm lub plab mus rau hauv cov hnyuv
Puas yog av ntsev acidic lossis alkaline?
Los ntawm kev txhais cov av saline tsis yog acidic. Nws yog alkaline. Alkaline av thiab dej muaj ph siab vim muaj ntsev. Ib qho av saline yog av ntsev
Puas yog Basalt acidic lossis alkaline?
Acidic pob zeb yog pob zeb uas yog siliceous, muaj cov ntsiab lus siab ntawm silica (SiO2), lossis pob zeb nrog pH qis. Ob lub ntsiab lus tsis sib npaug, piv txwv li, nyob rau hauv cov ntaub ntawv ntawm basalt, uas tsis yog siab pH (pib), tab sis qis hauv SiO2
Puas yog mercuric oxide yog qhov sib xyaw lossis cov khoom?
Mercury (II) oxide yog lwm qhov sib xyaw; Nws muaj cov ntsiab lus mercury thiab oxygen, thiab thaum cua sov nws decomposes rau cov ntsiab lus. Cov tshuaj sib txawv ntawm cov khoom sib xyaw uas cov ntsiab lus hauv cov khoom sib xyaw ua ke los ntawm cov ntawv cog lus tshuaj thiab tsis tuaj yeem sib cais los ntawm qhov sib txawv ntawm lawv lub cev
Puas yog ammonia daws acidic lossis alkaline?
Ammonia yog lub hauv paus tsis muaj zog vim tias nws cov nitrogen atom muaj ib khub electron uas tau txais ib qho proton. Tsis tas li ntawd, thaum yaj hauv dej, ammonia tau txais hydrogen ions los ntawm dej los tsim hydroxide thiab ammonium ions. Nws yog kev tsim cov hydroxide ions uas ua rau ammonia nws cov yam ntxwv hauv paus
