Cov qhov sib txawv ntawm peb txoj kev xav yog qhov Arrhenius theory hais tias cov kua qaub ib txwm muaj H + thiab qhov ntawd hauv paus ib txwm muaj OH-. Thaum lub Bronsted-Lowry qauv thov tias kua qaub yog cov neeg pub dawb proton thiab cov neeg txais kev lees paub yog li ntawd hauv paus tsis tas yuav muaj OH- yog li kua qaub pub ib tug proton rau dej ua H3O+.
Tib neeg kuj nug, qhov txawv ntawm Bronsted Lowry acid thiab lub hauv paus yog dab tsi?
Cov Brønsted - Lowry Kev xav ntawm Acids thiab Bases A Brønsted - Lowry acid yog ib tus neeg pub khoom noj proton (hydrogen ion). A Brønsted - Lowry puag yog ib tug proton (hydrogen ion) txais.
Tom qab ntawd, lo lus nug yog, qhov teeb meem tseem ceeb ntawm Arrhenius txhais li cas? (Kev zam rau txoj cai ua qhov tsis zoo Arrhenius txoj cai) Acids tsim hydronium ions thaum nws yaj hauv H2O. Muaj pH tsawg dua 7. Bases tsim hydroxide ions thaum yaj hauv H2O.
Kuj tseem paub yog, Arrhenius txhais li cas ntawm cov kua qaub thiab lub hauv paus?
Raws li txhais los ntawm Arrhenius , kua qaub - puag cov tshuaj tiv thaiv yog characterized los ntawm kua qaub , uas dissociate nyob rau hauv aqueous tov los tsim hydrogen ions (H+) thiab hauv paus , uas tsim hydroxide (OH−) cov. Cov kua qaub yog txhais raws li cov khoom sib xyaw lossis cov khoom uas tso tawm hydrogen (H+) ions rau hauv cov tshuaj (tsuas yog dej).
Dab tsi yog 3 lub ntsiab lus ntawm acids thiab bases?
Muaj peb loj classifications ntawm cov khoom hu ua kua qaub los yog hauv paus . Lub Arrhenius txhais hais tias ib kua qaub tsim H+ hauv kev daws teeb meem thiab a puag ua OH-. Cov no yog cov Brønsted-Lowry thiab Lewis Cov ntsiab lus ntawm acids thiab bases.

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
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
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
Dab tsi yog acids thiab bases raws li brønsted Lowry txoj kev xav?
Xyoo 1923, chemists Johannes Nicolaus Brønsted thiab Thomas Martin Lowry ntawm nws tus kheej tsim cov ntsiab lus ntawm cov kua qaub thiab cov hauv paus raws li cov khoom sib xyaw muaj peev xwm pub dawb los yog txais cov protons (H + ions). Hauv qhov kev xav no, cov kua qaub txhais tau tias yog cov neeg pub dawb; whereas bases txhais tau tias yog proton txais
