Tooj liab hydroxide

Tooj hydroxide compound (II) - yog ib tug kaj xiav muaju, tej zaum kuj muaj ib tug amorphous (hmoov) qauv. Nws yog insoluble nyob rau hauv dej, qhov kev soj ntsuam ntawm cov kev ruaj ntseg npe nruab nrab. Cov tshuaj mis ntawm lub substance - Cu (OH) ₂, nws yog ib tug tsis muaj zog puag, uas yog feem ntau tau los ntawm qhov kev txiav txim ntawm muaj zog los luj rau ntawm tooj liab ntsev.

Kev siv cov no compound yog dav faib nyob rau hauv ntau yam teb ntawm tshuaj thiab muaj ntau lawm. Yog li, cov tooj liab hydroxide siv raws li ib tug pigmenting tivthaiv nyob rau hauv lub tsom iav, tej hub khoom siv nyob rau hauv lub kos duab thiab jewellery, glazes. Pigmentation thaj chaw ntawm lub tebchaw muaj tau ntse siv nyob rau hauv qhov siv thiab ua high-resistant xim, uas yog siv rau daim ntawv thov mus rau hauv qab ntawm ships thiab txawm submarines, raws li qhov no tshuaj tiv thaiv fouling ntawm underwater qhov chaw ntawm ships algae thiab lwm yam dej ntsiab lwj hlau hlab ntsha.

Great zeem muag rau kev siv ntawm cov tshuaj yeeb dej caw nyob rau hauv niaj hnub hluav taws xob thiab hluav taws xob daim ntaub ntawv. Ntawm no, nws yuav ua ib tug indispensable tivthaiv ntawm high-kub superconductors raug technologies. Nyob rau hauv tas li ntawd, daim ntaub ntawv nyob rau hauv hluav taws xob engineering twb kuaj thaum lub sij hawm kuaj xyaum.

Ua tau nyob rau hauv cov tshuaj raug tooj liab hydroxide yog dav siv raws li ib lub hauv paus rau kev tshua tshuaj. Nyob rau hauv tas li ntawd nws yog tseem tau qhia kom meej thiab nyob rau hauv xws teb ntawm daim ntawv thov ntawm cov tshuaj yeeb dej caw, raws li ib tug kev npaj ntawm fodder rau tsiaj txhu, zus tau tej cov ntau yam qib ntawm cements, tshwj xeeb tshaj yog dai kom zoo nkauj (dawb lias) cements.

Txawm hais tias kev ruaj ntseg kev faib ntawm lub compound tsis yog ib tug heev tshuaj lom thiab tej tshuaj, ua hauj lwm nrog lawv yog tsim nyog los ua kom tiav tej yam tseem ceeb yuav tau ceev faj. Qhov no siv saum toj no tag nrho cov ua raws li lub cia tej yam kev mob ntawm teeb meem thiab tiv thaiv kom txhob nws los ntawm spilling mob ntawm cov tawm sab nraud. Yog hais tias qhov no tshwm sim, koj yuav tsum tam sim ntawd siv kev rho tawm qhov chaw wastage thiab pov tseg hydroxide mus rau ib tug muaj kev ruaj ntseg deb.

Raws li qhia los ntawm mis, tooj liab hydroxide - yog alkaline compound. Yog li ntawd tag nrho cov uas twb muaj lawm thiab yav tom ntej versions ntawm nws cov kev siv tswv yim, nws yog tshwm sim los ntawm alkaline zog.

Ua ntej teb cov lus nug, yuav ua li cas kom tau cov tooj liab hydroxide, yuav tsum tau ua ib tug reservation hais tias muaj ntau ntau xws xaiv.

Xav txog ib co ntawm cov feem ntau sawv daws yuav.

Cupric hydroxide yuav tau txais los ntawm nws cov sulfate. Qhov no tshuaj yog npaj meej soluble nyob rau hauv dej, dawb hmoov nrog ib tug crystalline qauv. Nws tshuaj mis - CuSO₄. Yog hais tias qhov no tshuaj hu ua tooj liab sulfate, yaj nyob rau hauv dej yuav tsum tau hla lub npe hu tooj liab sulfate. Ces, Yog hais tias mus no tov twb ntxiv ib qho alkali, cov tshuaj tiv thaiv no tshwm sim thaum lub sij hawm uas sawv tawm thiab Cu (OH) ₂ nyob rau hauv lub hauv daim ntawv ntawm ib tug precipitate ntawm xiav xim.

Hydroxide yuav muab tau los ntawm tooj liab nitrate (II), uas yog ib tug crystalline tshuaj muaj tsis muaj xim, nrog rau cov tshuaj mis Cu (NO₃) ₂. Yog hais tias qhov tshuaj tiv thaiv yog nqa tawm tau ib tug hydroxide, nws yog tsim nyog los NaOH tshuaj ntxiv tooj liab nitrate (II). Cov uas ua cov tshuaj tiv thaiv precipitate ntawm xim xiav yog cov yam tooj liab hydroxide.

Ib tug ntau txoj kev muab ib yam khoom thiab kev siv ntawm no tooj liab chloride (II), uas muaj cov tshuaj mis CuCl₂. Rau hydroxide yuav tsum daj hmoov uas yog tooj liab chloride yaj nyob rau hauv ib qhov nqi ntawm alkali. Thaum lub sij hawm xws tshua daj muaju ploj, thiab es tsis txhob ntog tag nrho cov tib tsim nyog peb precipitate xiav Hawj txawm - Cu (OH) ₂.
