Cov Cim Qhia Txog Acid-Base Ua Haujlwm Li Cas
Lub hauv paus ntsiab lus ntawm cov cim qhia txog cov kua qaub-puag hauv av zoo ib yam li cov cim qhia txog cov khoom siv hluavtaws: kev hloov xim thaum muaj kev cuam tshuam nrog cov kua qaub lossis cov hauv paus. Qhov kev hloov pauv no yog tshwm sim los ntawm qhov muaj cov xim ntuj hauv cov nroj tsuag uas teb rau kev hloov pauv hauv pH. Cov xim no, xws li anthocyanins, flavonoids, lossis betanin, muaj cov qauv tshuaj uas rhiab rau hydrogen ions (H +) thiab hydroxide ions (OH-).
Thaum cov kua qaub ntxiv rau hauv cov xim, cov qauv molecular hloov pauv, tsim cov xim tshwj xeeb. Ntawm qhov tod tes, thaum cov kua qaub tseem ceeb ntxiv rau hauv, cov qauv molecular hloov pauv dua, tsim cov xim sib txawv. Qhov no tso cai rau peb pom seb cov kua qaub puas yog acidic lossis basic.
Piv txwv ntawm Cov Qhia Txog Acid-Base Ntuj
1. Zaub qhwv liab
Zaub qhwv liab yog ib qho ntawm cov cim qhia txog ntuj uas siv ntau tshaj plaws. Zaub qhwv liab muaj cov xim anthocyanin uas hloov xim nyob ntawm pH ntawm cov kua. Hauv qab cov kua qaub, cov kua zaub qhwv liab yuav hloov liab lossis liab dawb.
