Acetic acid muaj 1 hloov tau hydrogen ion ib molecule ntawm cov kua qaub los yog koj tuaj yeem hais tias nws tsim tsuas yog ib qho hydrogen ion ib molecule ntawm cov kua qaub . Li no, lub Basicity ntawm acetic acid yog 1 los yog nws yog monobasic kua qaub.

Ib yam li ib tug yuav nug, dab tsi yog qhov tseem ceeb ntawm cov kua qaub?

Cov Basicity ntawm ib tug acid yog tus naj npawb ntawm hydrogen ions, uas tuaj yeem tsim los ntawm ib qho molecule ntawm cov kua qaub . Cov lus hauv qab no qhia qee yam kua qaub thiab lawv yooj yim.

Kuj Paub, ua li cas koj nrhiav tau lub hauv paus ntawm ib tug acid? Rau txiav txim seb ib yam khoom yog ib qho kua qaub los yog lub hauv paus, suav cov hydrogens ntawm txhua yam khoom ua ntej thiab tom qab cov tshuaj tiv thaiv. Yog hais tias tus naj npawb ntawm hydrogens tau txo cov tshuaj no kua qaub (paub hydrogen ions). Yog hais tias tus naj npawb ntawm hydrogens tau nce cov khoom ntawd yog lub hauv paus (lees txais hydrogen ions).

Hauv qhov no, kev siv acetic acid yog dab tsi?

Acetic acid yog siv raws li ib tug tshuaj reagent rau zus tau tej cov xov tooj ntawm chemical compounds. Nws yog feem ntau siv hauv kev tsim cov yas acetate monomer, acetic tshuaj anhydride thiab ester ntau lawm. 2. Purification ntawm cov organic tebchaw. Txhawm rau ntxuav cov organic sib txuas, acetic acid yog siv ua ib qho hnyav rau recrystallization.

Dab tsi yog pH ntawm acetic acid?

Acetic acid yog ib qho tsis muaj zog monoprotic kua qaub . Hauv cov kua dej aqueous, nws muaj pKib ua 4.76. Nws lub hauv paus conjugate yog acetate (CH3COO). A 1.0 M tov (hais txog qhov concentration ntawm domestic vinegar) muaj a pH ntawm 2.4, qhia tias tsuas yog 0.4% ntawm cov acetic acid molecules yog dissociated.
