Ib qho yog Arrhenius lub ntsiab lus, uas tig mus nyob ib puag ncig lub tswv yim tias cov kua qaub yog cov khoom uas ionize (so tawm) hauv cov tshuaj aqueous los tsim hydrogen (H+) ions thaum lub hauv paus tsim hydroxide (OH-) ions hauv kev daws.
Tsis tas li ntawd, dab tsi ions muaj acids?
Acids tsim hydrogen ions, H +, hauv dej. Bases tsim hydroxide ions, OH-.
Tsis tas li ntawd, puas yog tag nrho cov kua qaub muaj hydrogen ions? Tag nrho cov acids muaj hydrogen . Cov kua qaub dissociate hauv dej los tsim hydrogen ions . Hauv paus, kua qaub tsuas yog ionic compounds uas muaj hydrogen . Ib tug muaj zog kua qaub tag nrho ionizes, tawg mus rau hauv zoo hydrogen ions thiab tsis zoo them ions.
Kuj paub, dab tsi ion tam sim no nyob rau hauv tag nrho cov kev daws teeb meem acid?
Hydronium ion
Puas yog acidic thiab cov ntsiab lus daws teeb meem muaj ions?
Ions hauv acidic thiab yooj yim daws . Txhua yam dej kev daws teeb meem (nrog rau cov dej ntshiab) muaj hydroxide ions (formula OH -) thiab hydrogen ions (formula H +). Hydrogen ions muaj lub luag haujlwm rau acidity ntawm a daws :thaum a tshuaj muaj ntau hydrogen ions tshaj hydroxide ions ces cov daws yog acidic.

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
Dab tsi yog qee cov kua qaub hauv tsev thiab cov hauv paus?
Daim ntawv teev cov tsev Bases & Acids Baking Soda. Baking soda yog lub npe nrov rau sodium bicarbonate, paub tshuaj raws li NaHCO3. Diluted Soaps. Tsev neeg Ammonia. Tsev Neeg Vinegar. Citric Acid
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Cov piv txwv ntawm tsev neeg cov kua qaub thiab cov hauv paus yog dab tsi?
Daim ntawv teev cov tsev Bases & Acids Baking Soda. Baking soda yog lub npe nrov rau sodium bicarbonate, paub tshuaj raws li NaHCO3. Diluted Soaps. Tsev neeg Ammonia. Tsev Neeg Vinegar. Citric Acid
Dab tsi yog cov ions nyob rau hauv siab tshaj plaws concentration nyob rau hauv lub extracellular kua?
Cov tshuaj no nyob rau hauv cov kua dej extracellular thiab intracellular. Nyob rau hauv cov kua dej extracellular, cov cation loj yog sodium thiab cov anion loj yog chloride. Qhov loj cation nyob rau hauv cov kua dej intracellular yog poov tshuaj. Cov electrolytes no ua lub luag haujlwm tseem ceeb hauv kev tswj hwm homeostasis
