Qhov sib txawv tseem ceeb ntawm cov kua ammonia thiab cawv ammonia yog cov kua ammonia muaj NH3 molecules, thaum lub cawv ammonia muaj NH4OH.
Ob lub kua thiab cawv ammonia nyob hauv lub xeev ua kua. Lawv txawv ntawm ib leeg raws li cov tshuaj muaj pes tsawg leeg nrog rau cov tshuaj thiab lub cev.
Ua Kua Ammonia yog dab tsi?
Kua ammonia yog NH3 hauv lub xeev ua kua. NH3 yog ammonia. Nws muaj peb hydrogen atoms khi rau tib lub nitrogen atom. Tsis tas li ntawd, qhov sib xyaw no muaj ib leeg electron khub. Thiab, nws yog binary halide. Tsis tas li ntawd, qhov sib xyaw no tshwm sim raws li cov pa tsis muaj xim, thiab nws muaj pungent, irritating tsw. Lub geometry ntawm no compound yog trigonal pyramidal. Cov molar loj ntawm ammonia yog 17 g / mol.
Daim duab 01: Sib tov kua Ammonia nrog HCl Fumes kom tau Ammonium Chloride
Nyob rau hauv qhov xwm txheej, peb tuaj yeem pom cov pa roj no ua cov kab sib txuas tsim los ntawm cov khib nyiab nitrogen thiab cov tsiaj txhu thiab cov nroj tsuag. Thaum xav txog kev siv, kwv yees li 88% ntawm ammonia yog siv los ua chiv. Nws kuj tseem siv tau los ua ib qho precursor rau nitrogenous tebchaw. Hauv cov txheej txheem fermentation, ammonia muaj txiaj ntsig zoo li nitrogen qhov chaw rau cov kab mob. Aqueous ammonia kuj tseem ceeb raws li kev siv tshuaj ntxuav hauv tsev.
cawv Ammonia yog dab tsi?
cawv ammonia yog ammonia hauv dej. Yog li, cov tshuaj no muaj NH4OH molecules tsim los ntawm cov tshuaj tiv thaiv ntawm ammonia thiab dej molecules. Hauv cov ntsiab lus sib xws, peb muab cov tshuaj no ua cov tshuaj ammonia. Ntxiv mus, qhov tseeb denotation ntawm cov tshuaj no yog NH3(aq). Txawm li cas los xij, hauv cov kev daws teeb meem aqueous, ammonia molecules zoo li deprotonated vim cov nyhuv ntawm cov dej molecules thiab tshwm sim nyob rau hauv equilibrium nrog ammonium hydroxide. Yog li ntawd, thaum peb xa mus rau cawv ammonia, peb tab tom tham txog ammonium hydroxide tov. Cov molar loj ntawm cov tshuaj no tuaj yeem muab tau li 35.04 g / mol.
Thaum xav txog cov ntawv thov, cov tshuaj no yog ib qho tseem ceeb raws li kev siv tshuaj ntxuav hauv tsev, ua cov khoom ua ntej rau alkyl amines, hauv kev tsim khoom noj khoom haus raws li cov khoom lag luam leavening, kho straw rau nyuj, hauv kev tsim cov monochloramine, uas yog qhov tseem ceeb. ua tshuaj tua kab thiab lwm yam.
Dab tsi zoo sib xws ntawm Kua Ammonia thiab cawv Ammonia
- kua ammonia thiab cawv ammonia muaj NH3.
- Ob leeg yog ua kua.
- Lawv muaj txiaj ntsig zoo li cov tshuaj ntxuav.
Qhov txawv ntawm Liquid Ammonia thiab Liquor Ammonia yog dab tsi?
Ob lub kua thiab cawv ammonia nyob hauv lub xeev ua kua. Kua ammonia tsuas muaj ammonia molecules, tab sis cawv ammonia muaj ob qho ammonia thiab dej. Qhov sib txawv tseem ceeb ntawm kua ammonia thiab cawv ammonia yog cov kua ammonia muaj NH3 molecules thaum cawv ammonia muaj NH4OH. Tsis tas li ntawd, kua ammonia yog siv rau kev tsim cov chiv, raws li nitrogen qhov chaw rau cov kab mob hauv fermentation, thiab lwm yam thaum cawv ammonia yog ib qho tseem ceeb raws li ib tug huv tsev neeg, raws li ib tug precursor rau alkyl amines, nyob rau hauv cov zaub mov ntau lawm raws li ib tug leavening khoom, kho ntawm straw rau nyuj, thiab lwm yam.
Cov hauv qab no qhia txog qhov sib txawv ntawm cov kua ammonia thiab cawv ammonia.
Summary – Kua Ammonia vs Dej Ammonia
Ob lub kua thiab cawv ammonia nyob hauv lub xeev ua kua. Txawm li cas los xij, kua ammonia tsuas muaj ammonia molecules, tab sis cov cawv ammonia muaj ob qho ammonia thiab dej. Qhov sib txawv tseem ceeb ntawm kua ammonia thiab cawv ammonia yog cov kua ammonia muaj NH3 molecules, thaum cawv ammonia muaj NH4OH.
