Yog lawm, zinc ( Zn ) dissolves inhydrochloric acid (HCl). Zinc yog reactive ntau dua hydrogen, raws li cov reactivity series hais. Yog li ntawd, zinc candisplace hydrogen los ntawm HCl thiab tsim nws soluble chloride, uas yog, zinc chloride (ZnCl2). Thaum nws yog dilute, ces tsuas yog nws yuav muaj cov dej uas ZnCl2 yaj.
Tib neeg kuj nug, vim li cas Zinc hnov mob nrog hydrochloric acid?
Cov hlau zinc npaj txhij reacts nrog hydrochloric acid los tsim cov roj hydrogen (H2) thiab zinc chloride (ZnCl2). Txhua yam tshuaj tshuaj tiv thaiv los yog tsim orabsorbs tshav kub. Nyob rau hauv chemistry cov nyhuv no yog piav raws li tus tshuaj tiv thaiv enthalpy. Cov zinc tshuaj tiv thaiv ua kom sov thiab li no muaj qhov tsis zoo enthalpy.
Tom qab, lo lus nug yog, dab tsi yuav yaj zinc? Zinc yog insoluble nyob rau hauv dej tab sis reacts nkag nrog non-oxidising acids, sib sau zinc (II) thiab tso tawm hydrogen. Nws kuj yaj nyob rau hauv lub hauv paus muaj zog. Nws reactsreadily thaum rhuab nrog oxygen muab zinc oxide.
Kuj Paub, dab tsi tshwm sim rau hydrochloric acid thaum zinc ntxiv?
Zn + HCl = H2 + ZnCl2 Zinc yog oxidized (nws ua zoo) thiab wateris neutralized. Nws yog qhov txo qis-oxidation cov tshuaj tiv thaiv qhov twg ib qho ntawm cov reactants poob oxygen thiab lwm qhov nce. Yog li, teb koj cov lus nug, peb tau txais cov roj hydrogen thiab ntsev. Hydrogen gas, txheeb xyuas los ntawm kev nthuav tawm nws mus rau hluav taws kub.
Puas yog zinc chloride soluble hauv HCl?
Cov tshuaj tiv thaiv. Thaum zinc chloride yog heev soluble Hauv dej, cov kev daws teeb meem tsis tuaj yeem suav tias yog cov tshuaj daws tau yooj yim Zn 2+ ions thiab Cl− ions, ZnClxH2O(4−x)hom kuj muaj. Aqueous daws ntawm ZnCl2 areacidic: a 6 M aqueous tov muaj pH ntawm 1.

Yuav ua li cas yog tag nrho yaj yaj nyob rau hauv lub pas dej ua ke?
Koj cov khoom tawg tag nrho, lossis TDS, tus nqi yog qhov ntsuas ntawm tag nrho cov khoom uas yaj hauv koj lub pas dej. Cov pas dej da dej yuav tsum muaj qhov siab tshaj TDS tus nqi ntawm ib ncig ntawm 1,500 txog 2,000 ppm. Piv txwv li, cov dej haus tuaj yeem muaj qhov siab tshaj TDS tus nqi ntawm 500 ppm raws li EPA
Vim li cas cov xim cuam tshuam pom tseeb rau cov yeeb yaj kiab nyias dua li cov yeeb yaj kiab tuab?
Kev cuam tshuam ntawm lub teeb los ntawm sab sauv thiab sab qis ntawm cov xab npum lossis cov tshuaj ntxuav tes yog tshwm sim. Vim li cas cov xim cuam tshuam pom tseeb rau cov yeeb yaj kiab nyias dua li cov yeeb yaj kiab tuab? Vim yog kev cuam tshuam yoj, zaj duab xis ntawm cov roj ntawm dej hauv lub hnub ci pom tau tias daj rau cov neeg soj ntsuam ncaj qha saum lub dav hlau
Puas yuav zinc yaj hauv hydrochloric acid?
Yog lawm, zinc (Zn) dissolves inhydrochloric acid (HCl). Zinc yog ntau reactive dua hydrogen, raws li cov reactivity series hais. Yog li ntawd, zinccan tshem tawm hydrogen los ntawm HCl thiab tsim nws cov tshuaj chloride, uas yog, zinc chloride (ZnCl2)
Dab tsi ua rau cov npuas tsim thaum koj ntxiv cov hydrochloric acid rau zinc hlau?
Mercuric oxide. Mercury hlau. Thaum zincreacts nrog hydrochloric acid, cov tshuaj tiv thaiv bubblesvigorously li hydrogen gas yog tsim. Thaum zinc reacts nrog hydrochloric acid, lub raj kuaj ua kom sov asenergy yog tso tawm thaum lub sij hawm cov tshuaj tiv thaiv
Yuav ua li cas ua hydrochloric acid los ntawm sulfuric acid?
Ua ntej, koj yuav ncuav ib co ntsev rau hauv lub lauj kaub distil. Tom qab ntawd, koj yuav ntxiv ib co concentrated sulfuric acid rau ntsev. Tom ntej no, koj yuav cia cov no cuam tshuam nrog ib leeg. Koj yuav pib pom gasses npuas thiab cov roj hydrogen chloride tshaj tawm los ntawm lub raj sab saum toj
