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 ua tau nrog sodium hydroxide ua form ammonia gas (NH3), dej, thiab sodium chloride.
Ua raws li qhov xav tau, yuav ua li cas thaum ammonium chloride reacts nrog sodium hydroxide?
Cov tshuaj tiv thaiv nruab nrab Ammonium Chloride thiab Sodium hydroxide tsim ib co tshiab tebchaw zoo li Ammonia , Dej thiab Sodium Chloride . Hauv no tshuaj tiv thaiv thaum Ammonium Chloride reacts nrog Sodium hydroxide nyob rau hauv lub lab los tsim NH3 ( Ammonia ), NaCl ( Sodium Chloride ) thiab H2O (dej). Hauv no tshuaj tiv thaiv ammonia gas liberates.
Tsis tas li ntawd, ammonium hydroxide siv rau dab tsi? Ammonium hydroxide yog siv li tus neeg saib xyuas thiab tshuaj tua kab mob hauv ntau lub tsev thiab cov chaw ua haujlwm huv. Ammonium hydroxide kuj yog siv hauv kev tsim cov khoom xws li chiv, yas, rayon thiab roj hmab. Aqueous ammonia yog corrosive rau aluminium alloys, tooj liab, tooj liab alloys, thiab galvanized nto.
Tom qab ntawd, lo lus nug yog, ammonium hydroxide cuam tshuam li cas rau pH?
Xa mus rau daim duab 1, qee qhov ammonia yog tiag ionized rau ammonium ion, ua hydroxide anion raug tsim nyob rau hauv qhov sib npaug (stoichiometrically) hauv dej ntshiab los tsim Ammonium hydroxide . Saum toj no pH 7, qhov concentration ntawm hydroxyl anion (OH-) ua ntau dua hydronium, nce li pH ua ntau alkaline.
Yuav ua li cas thaum ammonium hydroxide rhuab?
Lab Safety Supply. Ammonium hydroxide (NH4OH) yog kev daws teeb meem ntawm ammonia hauv dej. Nws yog xim tsis muaj xim, ntshiab kua nrog pungent-rau-faint ammonia tsw. Nyob ruaj khov nyob rau hauv qhov kub thiab txias, cua sov nws tsim ammonia gas.

Dab tsi yog kev siv ammonium hydroxide?
ntxuav Kuj nug, lub luag haujlwm ntawm ammonium hydroxide yog dab tsi? Ammonium hydroxide yog alkaline, txhais tau tias nws muaj pH siab, yog li nws tuaj yeem siv los ua kom tsis muaj kua qaub. Ammoniumhydroxide muaj nyob rau hauv huab cua, dej, thiab av, thiab txawm nyob rau hauv tib neeg thiab nroj tsuag.
Dab tsi yog qhov tseeb ntawm cov ntsev tsim nyob rau hauv cov tshuaj tiv thaiv neutralization ntawm hydrochloric acid nrog barium hydroxide?
Lus Nug: Dab tsi yog cov qauv ntawm cov ntsev tsim nyob rau hauv Neutralization Reaction ntawm Hydrochloric Acid Nrog Barium Hydroxide? BaCl BaCl2 BaClH BaH2 BaO
Puas yog Aluminium React nrog nitric acid?
Qhov tseeb, nitric acid tsis hnov mob nrog txhuas. Nws yuav hnov tsuas yog thaum nitric dilute heev. Vim hais tias thaum txhuas los rau hauv kev sib cuag nrog nitric acid, ib txheej impervious ntawm txhuas oxide yog tsim. Yog li no txheej tiv thaiv thiab tiv thaiv ntxiv cov tshuaj tiv thaiv
Puas yog carboxylic acid react nrog 2 4 Dnph?
2,4-DNPH tsis hnov mob nrog amides, esters lossis carboxylic acids. Raws li qhia hauv qab no rau cov ntaub ntawv ntawm ester, ib qho ntxiv resonance qauv tuaj yeem kos rau 3 hom kev sib xyaw ua ke piv rau ketone
Puas yog phenol react nrog dej?
Koj tuaj yeem paub txog phenol vim tias: Nws yog ib qho yooj yim insoluble hauv dej. Nws reacts withsodium hydroxide tov kom muab cov xim tsis muaj xim (thiab yog li yuav tsum yog acidic). Nws tsis tsim cov pa roj carbon dioxide nrog sodium carbonate lossis hydrogencarbonate kev daws teeb meem (thiab yog li yuav tsum tsis muaj zog acidic)
