Qhov sib txawv tseem ceeb ntawm cov tshuaj tsis haum thiab cov ntsev hydrolysis yog cov tshuaj tsis haum yog cov kev daws teeb meem uas tuaj yeem tiv thaiv kev hloov pauv rau lawv cov pH nqi rau qee qhov, thaum ntsev hydrolysis yog tshuaj lom neeg cov tshuaj tiv thaiv uas tuaj yeem hloov pH ntawm cov tshuaj.
A tsis yog ib qho tshuaj aqueous uas zoo li tiv thaiv kev hloov pauv hauv pH. S alt hydrolysis yog cov tshuaj tiv thaiv uas muaj ib qho ntawm cov ions los ntawm cov ntsev reacting nrog dej, tsim ib qho acidic los yog yooj yim tov.
Dab tsi yog kev daws teeb meem?
A tsis yog ib qho tshuaj aqueous uas zoo li tiv thaiv kev hloov pauv hauv pH. Cov tshuaj no muaj ib tug sib tov ntawm ib tug qaug zog acid thiab nws conjugate puag los yog vice versa. Cov pH ntawm cov kev daws teeb meem no hloov me ntsis raws li qhov sib ntxiv ntawm cov kua qaub lossis lub hauv paus muaj zog.
Cov kua qaub tsis muaj zog (lossis lub hauv paus) thiab nws lub hauv paus conjugate (los yog conjugate acid) nyob rau hauv qhov sib npaug. Yog tias peb ntxiv qee cov kua qaub rau lub cev no, qhov sib npaug ntawm cov kua qaub, thiab nws tsim cov kua qaub ntau dua siv cov hydrogen ions tso tawm los ntawm cov kua qaub ntxiv. Txawm hais tias peb cia siab tias yuav nce cov hydrogen ions thaum ntxiv cov kua qaub uas muaj zog, nws tsis nce ntau. Ib yam li ntawd, yog tias peb ntxiv lub hauv paus muaj zog, cov hydrogen ion concentration txo qis dua li qhov xav tau rau qhov ntau ntawm alkali ntxiv. Peb tuaj yeem ntsuas qhov kev tiv thaiv pH hloov raws li lub peev xwm tsis muaj peev xwm. Lub peev xwm tsis ntsuas qhov tsis kam ntawm qhov tsis haum rau pH hloov ntawm qhov sib ntxiv ntawm OH– ions (ib puag ncig).
Daim duab 01: Tsis Muaj Peev Xwm
Thaum xav txog cov kev siv ntawm cov buffers, cov kev daws teeb meem no yog tsim nyog los khaws cov pH kom raug rau kev ua kom muaj zog hauv cov kab mob. Ntxiv mus, cov no yog siv nyob rau hauv kev lag luam hauv cov txheej txheem fermentation, teeb tsa cov xwm txheej raug rau dyes, hauv tshuaj ntsuam xyuas, ntsuas pH ntsuas, thiab lwm yam.
Ntshav Hydrolysis yog dab tsi?
Ntshav hydrolysis tuaj yeem piav qhia raws li cov tshuaj tiv thaiv uas muaj ib qho ntawm cov ions los ntawm cov ntsev uas cuam tshuam nrog dej, tsim cov kua qaub lossis cov tshuaj yooj yim. Yog tias cov ntsev tshwj xeeb yog tsim los ntawm cov tshuaj tiv thaiv nruab nrab ntawm cov kua qaub tsis muaj zog thiab lub hauv paus muaj zog, nws yuav ib txwm tsim cov tshuaj ntsev uas yog qhov yooj yim thaum nws nkag mus rau ntsev hydrolysis. Ntawm qhov tod tes, yog tias cov ntsev tshwj xeeb yog tsim los ntawm cov tshuaj tiv thaiv nruab nrab ntawm cov kua qaub uas muaj zog thiab lub hauv paus tsis muaj zog, nws yuav ib txwm tsim cov ntsev ntsev hauv cov ntsev hydrolysis. Ib yam li ntawd, yog tias qhov nruab nrab tshwm sim ntawm cov kua qaub thiab lub hauv paus muaj zog, cov kua ntsev tshwm sim yuav muaj pH 7 (qhov nruab nrab daws) thaum ntsev hydrolysis. Qhov no txhais tau tias cov ntsev nruab nrab tsis muaj ntsev hydrolysis.
Daim duab 02: Electrolysis: ntsev Hydrolysis Siv Hluav Taws Xob
Cov tshuaj tiv thaiv ntsev hydrolysis tuaj yeem piav qhia raws li kev rov qab nruab nrab. Yog tias peb ntxiv ntsev rau hauv dej, cov cation, anion, los yog ob qho tib si ions ntawm cov ntsev yuav hnov mob nrog dej, ua rau ib qho yooj yim los yog acidic tov raws li cov txheej txheem hydrolysis.
Dab tsi yog qhov sib txawv ntawm Buffer Solution thiab S alt Hydrolysis?
Tsis muaj kev daws teeb meem thiab ntsev hydrolysis yog cov ntsiab lus tseem ceeb hauv cov tshuaj inorganic thiab analytical chemistry. Qhov sib txawv tseem ceeb ntawm cov tshuaj tsis haum thiab cov ntsev hydrolysis yog cov kev daws teeb meem tsis yog cov kev daws teeb meem uas tuaj yeem tiv thaiv kev hloov pauv rau lawv cov pH nqi rau qee qhov, thaum ntsev hydrolysis yog tshuaj lom neeg cov tshuaj tiv thaiv uas tuaj yeem hloov pH ntawm cov tshuaj.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm cov tshuaj tsis haum thiab ntsev hydrolysis hauv daim ntawv teev npe rau ib sab ntawm kev sib piv.
Summary – Buffer Solution vs S alt Hydrolysis
A tsis yog ib qho tshuaj aqueous uas zoo li tiv thaiv kev hloov pauv hauv pH. S alt hydrolysis yog ib qho tshuaj tiv thaiv uas muaj ib qho ntawm cov ions los ntawm cov ntsev uas ua rau dej, tsim cov kua qaub los yog cov tshuaj yooj yim. Qhov sib txawv tseem ceeb ntawm cov tshuaj tsis haum thiab cov ntsev hydrolysis yog cov kev daws teeb meem tsis yog cov kev daws teeb meem uas tuaj yeem tiv thaiv ib qho kev hloov pauv rau lawv cov pH nqi rau qee qhov, hos ntsev hydrolysis yog tshuaj lom neeg cov tshuaj tiv thaiv uas tuaj yeem hloov pH ntawm cov tshuaj.
