Xiav thiab ntsuab yog cov yam ntxwv xim ntawm nickel compounds thiab lawv feem ntau hydrated. Nickel hydroxide feem ntau tshwm sim li ntsuab crystals uas tuaj yeem raug precipitated thaum aqueous alkali ntxiv rau kev daws ntawm nickel ( II ) ntsev. Nws yog insoluble hauv dej tab sis dissolves nkag tau hauv cov kua qaub thiab ammonium hydroxide.
Ib yam li ntawd, tib neeg nug, yog nickel hydroxide lub hauv paus?
Txog Nickel hydroxide hydroxide , ua OH- anion tsim los ntawm cov pa oxygen atom sib txuas rau hydrogen atom, feem ntau muaj nyob rau hauv cov xwm txheej thiab yog ib qho ntawm cov kev tshawb fawb ntau tshaj plaws hauv cov chemistry ntawm lub cev. Hydroxide compounds muaj ntau yam khoom thiab siv, los ntawm puag catalysis kom nrhiav tau cov pa roj carbon dioxide.
Tsis tas li ntawd, xim ntawm npib tsib xee yog dab tsi? nyiaj dawb
Qhov thib ob, yog nickel hydroxide aqueous?
Nickel (II) hydroxide yog inorganic compound nrog cov mis Ni (OH)2. Nws yog cov kua-ntsuab ntsuab uas yaj nrog decomposition hauv ammonia thiab amines thiab raug tawm tsam los ntawm acids.
Nickel (II) hydroxide.

Nickel hydroxide siv rau dab tsi?
Nickel hydroxide yog siv nyob rau hauv nickel -cadmium roj teeb thiab raws li ib tug tshuaj intermediary rau npib tsib xee catalysts thiab npib tsib xee ntsev. Lub hydrogenation ntawm finely hmoov ntawv xov xwm nrog a npib tsib xee hydroxide catalyst tsim hloov dua siab tshiab nyob rau hauv siab yields ntawm cellulose pub cov ntaub ntawv rau cov kua hydrocarbon fuels.

Puas yog npib tsib xee ib txwm muaj?
Native Elements. Minerals uas yog tsim los ntawm atoms los ntawm ib lub ntsiab lus raug xa mus rau cov ntsiab lus ib txwm muaj. Hauv pawg hlau, cov khoom nickel yog tib yam li hlau (muaj tib lub atomic radii) thiab tuaj yeem hloov pauv rau qee qhov ntawm nws. Qhov no yog hu ua solid-solution
Puas yog npib tsib xee ci los yog npub?
Nickel yog ib qho nyuaj, malleable, ductile hlau. Nws yog ci iab nyiaj hlau nrog me ntsis kub tinge uas yuav siv sij hawm ahigh polish thiab resists corrosion. Lub caij ua oxidize, tab sis txheej oxide tiv thaiv kev ua haujlwm ntxiv ntawm kev ua haujlwm Nws yog tus neeg xyuas pib ntawm hluav taws xob thiab cua sov
Cov xim dab tsi yog cov hlwb feem ntau ua ntej siv thawj cov xim rau cov txheej txheem Gram stain?
Ua ntej, siv lead ua violet, thawj stain, yog siv rau lub tshav kub-tso smear, muab tag nrho cov hlwb xim liab
