Dissolved hauv dej, nws tsis yog acidic tsis yog alkaline . Lub cev siv nws nyob rau hauv ntau cov txheej txheem, tshwj xeeb tshaj yog nitrogen excretion. Lub siab tsim nws los ntawm kev sib txuas ob ammoniamolecules (NH3) nrog carbon dioxide (CO2) nyob rau hauv molecule urea lub voj voog.
Yog li ntawd, urea puas nce pH?
Cov pH ntawm urea kev daws teeb meem. Nws tau raug lees paub tias urea nce qhov ntsuas pH ofaqueous daws. Los ntawm kev coj ua thiab pH Kev ntsuas onammonium hydroxide-ammonium chloride hauv urea daws, nws yog concluded tias urea nce ionization ntawm dej.
Kuj Paub, vim li cas urea yog organic compound? Urea (tseem hu ua carbamide) yog cov khoom pov tseg ntawm ntau cov kab mob nyob, thiab yog qhov loj organic ib feem ntawm tib neeg cov zis. Yog li, lub siab hloov cov ammonia mus rau qhov tsis muaj tshuaj lom compound , urea , uas tuaj yeem raug thauj mus los hauv cov ntshav mus rau lub raum kom nyab xeeb, qhov twg nws raug tshem tawm cov zis.
Ib sab saum toj no, tus nqi pH ntawm urea yog dab tsi?
kws kho mob. A 10% tov ntawm urea yield ib pH ntawm 7.2 (Merck Index, 11th Ed., p.9789).
Puas yog urea yog pab pawg ua haujlwm?
Urea , tseem hu ua carbamide, yog ib qho organiccompound nrog tshuaj formula CO (NH2) 2. Cov amide no muaj ob-NH2 pab pawg koom nrog carbonyl (C = O) pab pawg ua haujlwm . Urea yog dav siv nyob rau hauv chiv ua ib qhov chaw ntawm nitrogen (N) thiab yog ib qho tseem ceeb raw khoom rau chemicalindustry.

Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
Puas yog calcium cyanide yog cov kua qaub lossis lub hauv paus?
Calcium cyanide decomposes rau tsis tshua muaj tshuaj lom thiab flammable hydrogen cyanide thiab tshuaj lom thiab irritating nitrogen oxides thaum rhuab hauv hluav taws. QHOV 9. Lub cev thiab tshuaj lom neeg. Lub cev lub cev: Lub hauv paus ruaj khov: Reacts maj mam nrog dej los tsim calcium hydroxide, uas yog lub hauv paus muaj zog
Puas yog sodium hydrosulfide yog cov kua qaub lossis lub hauv paus?
Ib tug chemical puag. Reacts nrog cov kua qaub kom tso cov nplaim hluav taws thiab cov pa phem gaseous hydrogen sulfide. Tsuav yog cov tshuaj khaws cia muaj zog alkaline, pH> 10, muaj tsawg heev tso H2S. Ntawm pH = 7, qhov feem pua ntawm H2S tso tawm yog ze rau 80%
Puas yog Hydronium yog cov kua qaub lossis lub hauv paus?
Hauv cov tshuaj acidic, hydronium yog qhov ua haujlwm ntau dua, nws cov proton ntau dhau tau yooj yim rau cov tshuaj tiv thaiv nrog hom kab mob. Hydronium ion yog acidic heev: ntawm 25 ° C, nws pKa yog kwv yees li 0
Cov tshuaj ntxuav qhov cub puas yog cov kua qaub lossis cov hauv paus?
Ntau yam khoom siv tu, xws li xab npum thiab qhov cub ntxuav, yog cov hauv paus. Bases neutralize (tso tawm) acids. Alkalis yog cov hauv paus uas yaj hauv dej. Qhov ntau hydroxide ions ib lub hauv paus muaj, nws muaj zog dua
