Yog li, dej tsim nyog raws li cov khoom sib cais hauv dej los ua H + ions. Nws kuj tsim nyog raws li ib yam khoom uas dissociates hauv dej los ua OH- ions. Nws yog ob qho tib si an Arrhenius acid thiab Arrhenius puag thiab yog li tsuas yog Arrhenius amphoteric compound.
Vim li cas H2O yog Arrhenius acid?
Raws li txhais los ntawm Arrhenius: Ib qho Arrhenius acid yog ib yam khoom uas dissociates hauv dej los tsim hydrogen ions (H+) . Hauv lwm lo lus, ib qho kua qaub ua kom cov concentration ntawm H + ions hauv cov kua dej.
Puas tau dej suav tias yog kua qaub?
dej ntshiab tsis yog acidic lossis yooj yim; nws yog nruab nrab.
Puas yog dej yog kua qaub lossis hauv paus hauv Arrhenius?
lJ eo- Raws li Arrhenius system, dej tsis yog kua qaub los yog lub hauv paus.
pH sawv cev rau dab tsi?
pH yuav zoo li nws nyob ntawm lub sijhawm lub sijhawm ntawm cov ntsiab lus, tab sis nws yog ib chav ntsuas ntsuas. Cov ntawv luv pH sawv cev rau muaj peev xwm hydrogen, thiab nws qhia peb tias hydrogen nyob hauv cov kua dej ntau npaum li cas-thiab lub zog ntawm hydrogen ion yog li cas.
