Ib qho kev daws teeb meem ntawm ammonium hydroxide ntxiv mus rau ib tug daj ntseg xiav tov ntawm tooj liab sulfate , ua ib qho kev tawm tsam xiav precipitate uas tseem raug tshem tawm ze ntawm qhov chaw ntawm cov tshuaj.
Ua li no hauv kev txiav txim siab, yuav ua li cas thaum ammonium hydroxide ntxiv rau tooj liab sulphate tov?
Thaum twg ammonium hydroxide ntxiv nyob rau hauv me ntsis, ib tug daj ntseg xiav ppt yog tsim. Thaum dhau ntawm ammonium hydroxide ntxiv ces tsuas yog / tob xiav / azure xiav daws yog pom. A tooj liab sulphate kua reacts nrog ib tug hlau ntsia hlau tsim ib tug xiav kua thiab ib tug dub precipitate.
Ib sab saum toj, vim li cas tooj liab hydroxide yaj hauv ammonia? Thaum concentrated ammonia tshuaj (ammonium hydroxide ) yog ntxiv rau ib tug ntshiab, lub teeb xiav, aqueous tov ntawm tooj liab (II) chloride, hmoov, lub teeb xiav precipitate ntawm tooj liab (II) hydroxide daim ntawv. Ntxiv ntxiv ntawm ammonia ua rau tooj liab ion rov qab mus rau hauv kev daws raws li qhov sib sib zog nqus xiav ammonia complex.
Yog li ntawd, ua li cas thaum koj ntxiv ammonia rau tooj liab sulfate?
Ammonia reacts nrog tooj liab sulfate . Ammonia reacts nrog tooj liab sulfate . Thaum twg tooj liab (II) sulfate (CuSO4) yog yaj nyob rau hauv dej, nws tsim ib tug xiav aquo complex (hexaaquacopper (II), [Cu(H2O)6]2+). Thaum twg ammonia (NH4OH) yog nchuav rau hauv cov tshuaj, thaum xub thawj daj ntseg tooj liab hydroxide (Cu (OH) 2) precipitate yog tsim.
Dab tsi yog ammonium hydroxide react nrog?
Ammonium hydroxide reacts nrog tooj liab (II) chloride tsim khoom tooj liab (II) hydroxide , uas yog precipitate (ib qho khoom), thiab ammonium chloride, uas yog ntsev. Ammonium chloride, nyob rau hauv lem, tuaj yeem tiv nrog sodium hydroxide ua form ammonia gas (NH3), dej, thiab sodium chloride.

Yuav ua li cas thaum koj sib tov tooj liab thiab sulfur?
Thaum rhuab ua ke, tooj liab thiab sulfur sib xyaw ua ib qho sulfide ntawm tooj liab. Qhov ntau sulfurvaporizes tsim gaseous sulfur, uas khiav tawm ntawm lub crucible. Thaum cov roj sulfur kub ncav cuag huab cua, nws reacts nrog oxygen los tsim gaseous oxides ntawm leej faj (tsuas yog sulfur dioxide, SO2)
Yuav ua li cas rau tooj liab thaum nws rhuab?
Heated tooj liab hlau reacts nrog oxygen los tsim cov dub tooj liab oxide. Cov tooj liab oxide tuaj yeem cuam tshuam nrog cov roj hydrogen los tsim cov hlau thiab dej. Thaum lub funnel raug tshem tawm los ntawm hydrogen kwj, cov tooj liab tseem sov txaus kom oxidized los ntawm airagain
Yuav ua li cas thaum tooj liab carbonate yog rhuab heev?
Tshawb xyuas seb yuav ua li cas thaum cov khoom siv tooj liab carbonate yog cua sov. Thaum ntsuab tooj liab carbonate {CuCO3} rhuab nws decomposes tsim tooj liab oxide {CuO} thiab carbon dioxide {CO2}
Yuav ua li cas thaum tooj liab oxide reacts nrog sulfuric acid?
Reacting tooj liab (II) oxide nrog sulfuric acid. Nyob rau hauv qhov kev sim no ib qho insoluble hlau oxide reacted nrog ib tug dilute acid los ua ib tug soluble ntsev. Tooj liab (II) oxide, cov khoom dub, thiab tsis muaj xim dilute sulfuric acid react los tsim tooj liab (II) sulfate, muab cov xim xiav xim rau cov tshuaj
Vim li cas cov kab mob Gram tsis zoo tshwm liab liab thaum cov kab mob Gram zoo pom ntshav liab?
Gram zoo hlwb stain ntshav vim lawv cov peptotidoglycan txheej yog tuab txaus, txhais tau tias tag nrho cov kab mob Gram zoo yuav khaws lawv cov stain. Gram tsis zoo hlwb stain liab vim lawv muaj ib tug nyias peptidoglycan phab ntsa, thiab lawv yuav tsis khaws ib yam ntawm cov ntshav stain los ntawm crystal violet
