Qhov sib txawv tseem ceeb ntawm qhov kev txiav txim tsis muaj peev xwm thiab qhov tsis muaj peev xwm yog qhov kev txiav txim tsis yog hais txog lub peev xwm ntawm kev daws teeb meem los tiv thaiv kev hloov pauv hauv pH whereas tsis muaj peev xwm hais txog cov moles ntawm cov kua qaub lossis lub hauv paus xav tau los hloov pH ntawm cov tshuaj.

Cov tshuaj tsis haum yog cov tshuaj aqueous ua los ntawm cov kua qaub tsis muaj zog thiab nws lub hauv paus conjugate. Cov ntsiab lus tsis ua haujlwm thiab tsis muaj peev xwm piav qhia txog cov khoom ntawm cov kev daws teeb meem uas tuaj yeem ua raws li buffers.

Dab tsi yog Kev Ua Tsis Txaus Siab?

Buffer action yog lub peev xwm ntawm kev daws teeb meem los tiv thaiv kev hloov pauv hauv pH. Qhov sib ntxiv ntawm ib qho nyiaj ntawm cov kua qaub los yog lub hauv paus rau cov tshuaj tsis tuaj yeem hloov pH ntawm cov tshuaj tsis haum. Qhov kev txiav txim tsis yog hais txog kev muaj peev xwm nyob twj ywm tsis hloov thaum ntxiv me me ntawm cov kua qaub lossis cov hauv paus. Cov kev daws teeb meem uas tuaj yeem pom qhov muaj peev xwm no hu ua buffer solutions lossis yooj yim li buffers.

Tsis tas li ntawd, qhov tshwm sim no tseem ceeb heev; Yog tias peb coj cov dej ua piv txwv, nws lub peev xwm nyob twj ywm tsis hloov pauv thaum ntxiv cov kua qaub lossis lub hauv paus rau qee qhov yuav pab ua kom nws cov nqi hauv kev ua haujlwm ntawm cov kab mob lom.

Dab tsi yog Buffer Capacity?

Tsis muaj peev xwm hais txog moles ntawm cov kua qaub lossis lub hauv paus xav tau los hloov pH ntawm cov tshuaj. Nws yog qhov ntsuas kom muaj nuj nqis hais txog qhov tsis kam ntawm pH hloov ntawm kev ntxiv lossis txo cov hydroxide ions lossis hydrogen ions. Peb tuaj yeem xam tus nqi no los ntawm kev faib cov kua qaub lossis lub hauv paus xav tau los hloov pH ntawm qhov tsis sib xws los ntawm kev hloov pH thiab qhov ntim ntawm cov tshuaj tsis haum.

A cov tshuaj tau txais lub peev xwm no vim yog kev noj cov kua qaub lossis cov hauv paus ntxiv rau cov tshuaj tsis haum los ntawm tus neeg sawv cev buffering tam sim no hauv cov tshuaj ntawd. Cov kev daws teeb meem tsis muaj qhov sib npaug ntawm cov kua qaub thiab lawv lub hauv paus conjugate lossis vice versa. Yog li ntawd, p-H yuav tsis hloov pauv thaum ntxiv cov kua qaub ntxiv los yog lub hauv paus rau qee qhov ntev npaum li tus neeg sawv cev buffering tsis ua tiav (nyob rau hauv qhov sib npaug). Feem ntau, peb tuaj yeem suav cov peev txheej buffering siv txoj hauv kev titrimetric.

Qhov txawv ntawm Buffer Action thiab Buffer Capacity yog dab tsi?

Cov tshuaj tsis haum yog cov tshuaj aqueous ua los ntawm cov kua qaub tsis muaj zog thiab nws lub hauv paus conjugate. Cov ntsiab lus buffer action thiab buffer muaj peev xwm yog cov ntsiab lus siv rau cov kev daws teeb meem uas tuaj yeem ua raws li buffers. Qhov sib txawv tseem ceeb ntawm qhov kev txiav txim tsis muaj peev xwm thiab tsis muaj peev xwm yog qhov kev txiav txim tsis yog hais txog lub peev xwm ntawm kev daws teeb meem los tiv thaiv kev hloov pauv hauv pH whereas tsis muaj peev xwm hais txog cov moles ntawm cov kua qaub lossis lub hauv paus yuav tsum tau hloov pH ntawm cov tshuaj.

Hauv qab infographic qhia txog qhov sib txawv ntawm qhov kev ua tsis tau thiab tsis muaj peev xwm.

Summary – Buffer Action vs Buffer Capacity

Cov tshuaj tsis haum yog cov tshuaj aqueous uas ua los ntawm cov kua qaub tsis muaj zog thiab nws lub hauv paus conjugate. Cov ntsiab lus buffer action thiab tsis muaj peev xwm yog siv feem ntau hais txog cov kev daws teeb meem uas tuaj yeem ua raws li buffers. Qhov sib txawv tseem ceeb ntawm qhov kev txiav txim tsis muaj peev xwm thiab tsis muaj peev xwm yog qhov kev txiav txim tsis yog hais txog lub peev xwm ntawm kev daws teeb meem los tiv thaiv kev hloov pauv hauv pH whereas tsis muaj peev xwm hais txog cov moles ntawm cov kua qaub lossis lub hauv paus xav tau los hloov pH ntawm cov tshuaj.
