Acids thiab bases yog yus muaj zog los tsis muaj zog. Ib tug muaj zog kua qaub los yog muaj zog puag tag nrho dissociates rau hauv nws cov ions hauv dej. Yog hais tias lub compound tsis tag dissociate, nws yog ib tug qaug zog kua qaub los yog puag . Cov kua qaub tig litmus ntawv liab, thaum hauv paus tig litmus ntawv xiav. Cov tshuaj nruab nrab yuav tsis hloov daim ntawv xim.
Tib neeg kuj nug, dab tsi yog qhov tseeb txog cov kua qaub thiab cov hauv paus?
Acid los yog puag " zog "yog ib qho kev ntsuas ntawm qhov yooj yim ntawm cov molecule ionizes hauv dej.
Bond Lub zog Txoj Cai.
| Tag nrho cov yam ntxwv ntawm cov kua qaub thiab cov hauv paus muaj feem cuam tshuam txog seb cov ntawv tseem ceeb yog cov molecules thiab ions. | ||
|---|---|---|
| Kev coj ua | muaj zog | qaug zog |
| Bond Strength | qaug zog | muaj zog |
Ib yam li ntawd, acids thiab bases hauv chemistry yog dab tsi? Hauv chemistry , acids thiab bases tau raug txhais txawv los ntawm peb pawg ntawm kev xav. Ib qho yog Arrhenius txhais, uas tig los ntawm lub tswv yim ntawd kua qaub yog cov khoom uas ionize (so tawm) nyob rau hauv ib tug aqueous tov los tsim hydrogen (H+) ions thaum hauv paus tsim hydroxide (OH-) ions hauv kev daws.
Hauv qhov no, vim li cas nws tseem ceeb kom paub cov kua qaub thiab cov hauv paus?
Acids thiab bases yog qhov tseem ceeb heev rau tib neeg lub cev. Lawv ua haujlwm kom sib npaug pH qib hauv lub cev. Tsis sib npaug acids thiab bases tuaj yeem ua rau muaj ntau yam teeb meem hauv lub cev. Feem ntau tseem ceeb yam balancing acids thiab bases yog tias cov ntshav tau txais txoj kev ncig mus rau lub cev.
Dab tsi yog qhov txawv ntawm acids thiab bases?
Ntsiab txawv : Acids thiab bases yog ob hom corrosive. Txhua yam khoom nrog tus nqi pH nruab nrab 0 txog 7 yog suav tias yog acidic, qhov pH tus nqi ntawm 7 txog 14 yog a puag . Cov kua qaub yog cov ionic tebchaw uas sib cais hauv dej los tsim cov hydrogen ion (H +).

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Vim li cas qhov tseeb thiab qhov tseeb yog qhov tseem ceeb hauv kev tshawb fawb?
Qhov tseeb sawv cev rau qhov kev ntsuas ze npaum li cas los ntawm nws qhov tseeb. Qhov no yog qhov tseem ceeb vim tias cov cuab yeej tsis zoo, cov ntaub ntawv ua haujlwm tsis zoo lossis tib neeg yuam kev tuaj yeem ua rau cov txiaj ntsig tsis raug uas tsis ze rau qhov tseeb. Precision yog qhov ze npaum li cas ntawm cov kev ntsuas ntawm tib yam yog rau ib leeg
Dab tsi yog qhov txawv ntawm Arrhenius txhais thiab brønsted Lowry txhais ntawm acids thiab bases?
Qhov txawv ntawm peb txoj kev xav yog qhov kev xav Arrhenius hais tias cov kua qaub ib txwm muaj H + thiab cov hauv paus ib txwm muaj OH-. Thaum tus qauv Bronsted-Lowry thov tias cov kua qaub yog cov neeg pub dawb proton thiab cov neeg txais kev lees paub yog li cov hauv paus tsis tas yuav muaj OH- yog li cov kua qaub pub ib qho proton rau dej tsim H3O +
Dab tsi yog Arrhenius lub tswv yim ntawm acids thiab bases?
Lub tswv yim Arrhenius acid-base cais cov khoom ua kua qaub yog tias nws tsim hydrogen ions H (+) lossis hydronium ions hauv dej. Ib yam khoom raug cais raws li lub hauv paus yog tias nws tsim hydroxide ions OH (-) hauv dej. Lwm txoj hauv kev ntawm kev faib cov tshuaj raws li cov kua qaub lossis cov hauv paus yog lub tswv yim Bronsted-Lowry thiab Lewis lub tswv yim
