Zinc nitrate

Muaj ntau ntawm peb tsis paub lub Science News for KIDS yog zoo meej, tab sis nyob rau hauv lub neej txhua hnub peb cas muaj nrog cov khoom thiab cov ntaub ntawv uas ua los ntawm cov tshuaj txhais tau tias. Nyob rau hauv no tsab xov xwm peb yuav kub siab rau zinc nitrate, yam uas yog yog ib qhov nyuaj rau xav txog tej yam rau tag nrho cov hav zoov ntawm ib co cov nplais ntawm kev khwv nyiaj txiag. zinc nitrate yog ib tug tsis muaj kob muaju, lub resulting compound ntawm hydroxide, oxide los yog zinc carbonate nrog nitric acid. Cov uas ua crystalline hydrates, tsis zoo li tus pib cov ntaub ntawv, nkag soluble nyob rau hauv dej cawv thiab dej. Tsaug rau cov zog uas zinc nitrate twb varied.

Cov neeg siv nws tsis tsuas nyob rau hauv cov tshuaj lub chaw soj nstuam, tab sis kuj nyob rau hauv lub neej txhua hnub, tej zaum tsis muaj txawm xav txog tej yam lawv siv. zinc nitrate yog pom nyob rau hauv ntau cov khoom uas cov neeg siv nyob rau hauv teb. Nyob rau hauv tas li ntawd, qhov no tshuaj yog ib tug tswv cuab ntawm cov loj Cheebtsam ntawm ntau cov cuab yeej siv lub sij hawm ntau ua hauj lwm. Zinc oxide yog ib tug hmoov ntawm ib tug pob tshab xim, muaj raws ntawm ib tug plurality ntawm me me muaju. Nco ntsoov hais tias cov khoom ntawm zinc thiab zinc nitrate yog txawv heev, yog li no ib feem tsis yog soluble nyob rau hauv cov dej thiab yuav siv sij hawm nyob rau hauv ib tug daj tinge thaum nws yog rhuab.

Hydroxides kuj tsis zoo soluble nyob rau hauv dej, lawv tsis pom kev zoo li oxide - ib tug tsis muaj kob hmoov. Txawm li cas los, lub ntsiab kom zoo dua ntawm lub hydroxide yog hais tias nws yog amorphous, thaum ua ke nrog cov dej, nws exhibits ib tug xov tooj ntawm amphoteric zog. Zinc carbonate kiag insoluble nyob rau hauv dej thiab decomposes thaum rhuab nquag. Thaum lub sij hawm lub tebchaw uas muaj npe tshuaj nrog nitric acid yog npaj crystalline hydrates. Scope ntawm zinc nitrate twb varied. Dhau li microchemistry cov tshuaj yuav tsum nyob rau hauv lub neej txhua hnub. zinc nitrate yog siv rau cov kev tiv thaiv kev kho mob ntawm cov iron thiab steel, txij li thaum zinc ceev thiab cov kev ceev ntawm steel yog sib txawv. Tom qab lub tshav kub kev kho mob ntawm steel chaw, nws ua ntau zog thiab tsawg raug rau phiv los ntawm qhov chaw.

Nws occupies ib tug tshwj xeeb qhov chaw ntawm zinc nyob rau hauv lub teb ntawm aviation. Los ntawm xws ua, txo hlau xeb thiab tsub kom nws kav ntev. Ntxiv mus, lub cim thaj chaw ntawm zinc nitrate siv teb amateurs. Nyob rau hauv cov ntaub ntawv no, lub tshuaj yog ib feem ntawm ib tug ntau yam ntawm chiv rau cov av. Thiab lawv yog siv nyob rau hauv yuav luag tag nrho cov thoob lub ntiaj teb, txij thaum nws yog zoo pov thawj, thiab lawv nqi yog tsawg tshaj li uas ntawm lawv cov counterparts los ntawm lwm yam ntaub ntawv. Yog li zinc nitrate tsis ntxim rau tib neeg kiag li tsis ntxim nyob rau hauv cov ntaub ntawv no, nws yog harmless. Nroj tsuag raug muab tshem tawm los ntawm ib tug nitrogen chiv, uas yog yuav tsum tau rau lawv cov kev loj hlob. Txawm li cas los, cov kev siv ntawm tshuaj muaj zinc nitrate yuav tsum ua tib zoo kho proportions. Cov kev puas tsuaj rau cov nroj tsuag tej zaum yuav tsum muaj ntaub ntawv raws li ib tug yuav txo tau nyob rau hauv lub koob tshuaj zinc thiab nws nce.

Nyob rau hauv thawj cov ntaub ntawv, cov kab nuv ntses yuav puas, uas txhais tau tias cov kev tsim tshwm sim yuav tsis tau tiav thiab cov gardener los yog neeg ua teb yuav raug kev txom nyem ib co losses. Nyob rau hauv lub thib ob cov ntaub ntawv, thaum lub zinc nitrate ntau npaum li cas, yuav muaj ib undesirable nyhuv uas tseem cuam tshuam rau txoj kev loj hlob ntawm cov nroj tsuag thiab tau txais cov sau. Lwm cheeb tsam ntawm daim ntawv thov ntawm zinc nitrate - explosives uas tsis muaj tshwj xeeb tshaj yog loj loj puas yam. Tej tebchaw yog feem ntau siv rau ua, piv txwv li, siv ua hauj lwm, thaum koj xav tau kom sai thiab kuj cheaply rau muab rho qhov no los yog tus kwv. Zinc nitrate nyob rau hauv cov tshuaj tiv thaiv nrog rau lwm cov tshuaj thiab tej zaum yuav tawg los ntawm tiv cav tseb thiab nrog rau cov kev pab los ntawm laser. Heev feem ntau nws yog siv thiab rau kev tshuaj thwmsim.
