Xyoo 1923, chemists Johannes Nicolaus Brønsted thiab Thomas Martin Lowry ywj siab tsim cov ntsiab lus ntawm acids thiab bases Raws li cov tebchaw muaj peev xwm pub dawb lossis txais cov protons (H + ions). Hauv no kev xav , kua qaub txhais tau tias yog cov neeg pub dawb proton; hos hauv paus txhais tau tias yog proton txais.

Kuj nug, Bronsted Lowry acid puag yog dab tsi?

Brønsted - Lowry Acid - Base Reactions . Ib kua qaub - puag cov tshuaj tiv thaiv raws li cov Brønsted - Lowry Lub ntsiab txhais yog kev hloov ntawm ib tug proton los ntawm ib tug molecule los yog ion mus rau lwm tus. Thaum ammonia yaj nyob rau hauv dej, nws undergoes cov nram qab no reversible tshuaj tiv thaiv.

Kuj Paub, Bronsted Lowry cov ntsiab lus ntawm cov kua qaub thiab lub hauv paus quizlet yog dab tsi? A Brosted - Lowry Acid yog ib tug compound uas pub ib tug proton (H + ion). A Brosted - Lowry Base yog ib tug compound uas txais ib tug proton (H + ion). Muaj zog kua qaub . Ib tug muaj zog kua qaub tag nrho dissociates rau hauv H + ion (s) thiab anion thaum yaj hauv dej. Qhov no kuj ua rau muaj zog kua qaub muaj zog electrolyte.

Ib yam li ntawd, dab tsi yog acid raws li bronsted?

A Brosted -Lowry kua qaub yog ib yam khoom uas pub ib tug proton nyob rau hauv daim ntawv ntawm ib tug hydrogen ion. Cov Brosted -Lowry puag, nyob rau hauv lem, lees txais no proton, thiab cov khoom tshwm sim yog ib tug conjugate kua qaub thiab lub hauv paus conjugate.

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.
