ntsev a tsis muaj zog acid thiab muaj zog puag undergoes hydrolysis hauv dej rau tsim khoom ntxiv OH- ions. Txij li acetic kua qaub yog a qaug zog acid , nws tseem unionized nyob rau hauv kev daws thiab cov OH-ions ua cov tshuaj yooj yim los yog alkaline. Ib yam li ntawd, ntsev ntawm a muaj zog acid thiab tsis muaj zog puag yog acidic nyob rau hauv aqueous tov.

Ua raws li qhov no hauv kev xav, yuav ua li cas tshwm sim thaum lub zog acid tsis muaj zog nrog lub hauv paus muaj zog?

A qaug zog acid yuav react nrog lub hauv paus muaj zog los tsim ib qho yooj yim (pH> 7) tov.

Tom qab, lo lus nug yog, dab tsi yog qhov muaj zog acid thiab muaj zog puag tsim? Hauv a muaj zog acid - muaj zog hauv paus titration , cov kua qaub thiab base yuav react los tsim ib qho kev daws teeb meem. Ib qho piv txwv ntawm qhov no yuav ua tus titration ntawm hydrochloric kua qaub ( muaj zog acid thiab sodium hydroxide ( lub hauv paus muaj zog ) los tsim sodium chloride thiab dej. Tsim los ntawm Jay.

Ua raws li qhov no hauv kev xav, dab tsi yog qhov tsis muaj zog acid thiab lub hauv paus tsis muaj zog tsim?

Cov tshuaj tiv thaiv nruab nrab yog thaum kua qaub thiab a puag react tsim dej thiab ntsev thiab koom nrog kev sib xyaw ntawm H + ions thiab OH- ions los tsim dej.

Dab tsi qhia yog siv rau qaug zog acid thiab muaj zog puag?

Qhov pH ntau ntawm phenolphthalein yog li ntawm 8.3 txog 10.0, tab sis qhov titration nkhaus yog qhov tob heev ntawm qhov sib npaug ntawm qhov sib npaug. phenolphthalein ua qhov taw qhia zoo. Rau qhov muaj zog hauv paus-tsis muaj zog acid titration, qhov sib npaug taw tes yog nyob ze pH 9. Phenolphthalein yog qhov zoo rau qhov titration no.
