A Brosted - Lowry acid yog ib hom tshuaj uas pub ib lossis ntau dua hydrogen ions hauv cov tshuaj tiv thaiv. Piv txwv li, a Brosted - Lowry puag txais hydrogen ions. Thaum nws pub nws cov proton, cov kua qaub ua nws cov conjugate puag . Ib qho kev saib ntau dua ntawm txoj kev xav yog cov kua qaub ua tus pub rau proton thiab a puag raws li ib tug proton txais.

Ib yam li ntawd, Bronsted Lowry txhais li cas ntawm lub hauv paus?

Peb xa mus rau cov kev daws teeb meem no Brosted - Lowry puag . A Brosted - Lowry puag yog ib qho kev daws teeb meem uas coj tus cwj pwm zoo li proton txais, thiab cov protons yog nyob rau hauv daim ntawv ntawm hydrogen (H +) ion. Cov tshuaj uas coj tus cwj pwm zoo li tus neeg pub dawb proton hu ua a Brosted - Lowry kua qaub.

Tsis tas li ntawd, qhov txawv ntawm Arrhenius txhais thiab brønsted Lowry txhais ntawm acids thiab bases yog dab tsi? 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+.

Qhov thib ob, lub ntsiab lus ntawm cov kua qaub raws li Bronsted Lowry yog dab tsi?

A Brosted - Lowry acid yog ib hom tshuaj uas pub ib lossis ntau dua hydrogen ions hauv cov tshuaj tiv thaiv. Piv txwv li, a Brosted - Lowry puag txais hydrogen ions. Thaum nws pub nws cov proton, lub kua qaub ua nws lub hauv paus conjugate. Ib qho kev saib ntau dua ntawm txoj kev xav yog ib qho kua qaub raws li tus neeg pub khoom noj proton thiab lub hauv paus ua tus txais proton.

Bronsted puag muab piv txwv li cas?

Acetic acid (CH3COOH) yog cov Brosted - Lowry acid vim tias nws yog tus pub dawb proton - nws pub nws cov hydrogen ion rau dej. Dej yog qhov Brosted -Lowry puag vim nws yog proton txais. Lub conjugate puag yog CH3COO- vim nws yog cov khoom tsim tom qab cov proton, hydrogen, pub dawb.
