Ntxiv ib qho kua qaub nce qhov concentration ntawm H3O+ ions hauv kev daws teeb meem. Ntxiv ib puag txo qhov concentration ntawm H3O+ ions hauv kev daws teeb meem. Ib kua qaub thiab a puag zoo li chemical opposites. Yog ib puag yog ntxiv rau ib acidic kev daws, kev daws yuav tsawg dua acidic thiab txav mus rau nruab nrab ntawm pH nplai.
Hais txog qhov no, yuav ua li cas thaum koj ntxiv cov kua qaub rau hauv lub hauv paus?
Thaum ib kua qaub thiab a puag muab tso ua ke, lawv hnov qab neutralize lub kua qaub thiab puag khoom, ua ib tug ntsev. Lub H(+) cation ntawm lub kua qaub ua ke nrog OH(-) anion ntawm lub puag tsim dej. Lub compound tsim los ntawm cation ntawm lub puag thiab anion ntawm lub kua qaub hu ua ntsev.
Ib tug kuj nug, koj puas ntxiv puag rau dej lossis dej rau hauv paus? Ib txwm dilute puag daws los ntawm ntxiv puag rau dej thiab tsis dej rau hauv paus . Ntxiv dej kom concentrated hauv paus tuaj yeem ua rau muaj kev kub ntxhov ntawm cov tshuaj thiab txaws. Ammonium hydroxide yuav tsum yuav tsum tau ua nyob rau hauv ib tug tshuaj fume hood kom tsis txhob ua pa ammonia gas.
Ib yam li ntawd, nws raug nug, nws puas yog acid rau hauv paus lossis puag rau acid?
Yog tias koj xav dilute cov kua qaub nrog dej ua ntej neutralizing nws nrog lub hauv paus (piv txwv li, sodium hydroxide , potassium hydroxide lossis sodium bicarbonate), ib txwm ntxiv kua qaub rau hauv dej; tsis txhob ntxiv dej rau acid.
Puas yog ob lub acids ua lub hauv paus?
Yog lawm. Ib kua qaub ua haujlwm li a puag . Noj sulfuric kua qaub thiab nitric kua qaub piv txwv. Ob leeg muaj zog kua qaub Thaum xav txog lawv ionization hauv dej.

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 cov kua qaub lossis lub hauv paus?
F- yog lub hauv paus rau hydrofluoric acid. Muaj kev sib raug zoo ntawm lub zog. Tsis muaj sodium lossis chloride ions tsis muaj kev cuam tshuam nrog dej. Yog li thaum cov 2 sib cuam tshuam, lub hauv paus muaj zog dominates
Puas yog urea yog cov kua qaub lossis lub hauv paus?
Dissolved hauv dej, nws tsis yog acidic noralkaline. 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) molecule nyob rau hauv lub voj voog urea
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%
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
