Qhov sib txawv tseem ceeb ntawm titration thiab neutralization yog tias titration yog ib qho kev tshuaj ntsuam xyuas, whereas neutralization yog tshuaj tiv thaiv.
Titration thiab neutralization yog cov ntsiab lus tseem ceeb hauv chemistry. Titration yog ib qho txheej txheem uas yuav tsum tau muaj cov cuab yeej tshwj xeeb, thiab nws ua raws li cov tshuaj tiv thaiv nruab nrab. Neutralization cov tshuaj tiv thaiv yog cov tshuaj tiv thaiv uas cov acidity yog sib npaug los ntawm kev sib ntxiv ntawm lub hauv paus los yog vice versa kom tau ib tug nruab nrab tov.
Titration yog dab tsi?
Titration yog cov txheej txheem tshuaj ntsuam xyuas uas muaj txiaj ntsig zoo hauv kev ntsuas qhov concentration ntawm cov tshuaj lom neeg. Peb tuaj yeem ua qhov no siv cov kev daws teeb meem uas muaj qhov paub txog qhov tseeb. Cov txheej txheem titration yuav tsum muaj cov cuab yeej tshwj xeeb.
Nyob rau hauv ib lub titration apparatus, muaj ib tug burette uas feem ntau muaj cov txheej txheem tov nrog ib tug paub concentration. Yog hais tias cov tshuaj nyob rau hauv lub burette tsis yog ib tug qauv kev daws teeb meem, nws yuav tsum tau standardized siv tus qauv thawj. Lub raj mis titration yog sau nrog ib qho piv txwv ntawm cov tshuaj tiv thaiv uas tsis paub meej. Yog hais tias tus qauv kev daws teeb meem (hauv burette) tsis tuaj yeem ua tus taw qhia tus kheej, peb yuav tsum ntxiv qhov ntsuas qhov tsim nyog rau tus qauv hauv lub khob titration.

Thaum lub sijhawm titration, cov txheej txheem kev daws teeb meem tau ntxiv rau lub khob maj mam kom txog thaum muaj xim hloov. Cov xim hloov ntawm cov tshuaj analytes qhia qhov kawg ntawm titration. Txawm hais tias nws tsis yog qhov tseeb ntawm qhov kawg ntawm qhov titration, peb tuaj yeem xav tias nws yog qhov sib npaug ntawm qhov sib npaug vim tias tsuas muaj qhov sib txawv me ntsis (qhov sib npaug taw tes yog qhov taw tes qhov twg cov tshuaj tiv thaiv tiag tiag nres).
Kev nyeem ntawv burette yog qhov muaj txiaj ntsig los txiav txim siab tus qauv kev daws teeb meem uas cuam tshuam nrog cov qauv. Tom qab ntawd los ntawm kev siv tshuaj tiv thaiv thiab kev sib raug zoo ntawm stoichiometric, peb tuaj yeem xam qhov concentration ntawm qhov tsis paub.
Neutralization yog dab tsi?
Lub sij hawm neutralization yog hais txog cov tshuaj tiv thaiv ntawm cov kua qaub thiab lub hauv paus, uas tsim cov tshuaj nruab nrab. Qhov pH ntawm qhov nruab nrab yog pH=7. Cov tshuaj tiv thaiv neutralization muaj kev sib xyaw ua ke ntawm H+ ions thiab OH– ions los tsim cov dej molecules.

Yog tias qhov kawg pH ntawm cov kua qaub thiab cov tshuaj tiv thaiv sib xyaw yog 7, qhov ntawd txhais tau tias sib npaug ntawm H+ thiab OH– ions tau reacted nyob rau hauv no cov tshuaj tiv thaiv (kom tsim ib tug dej molecule ib H+ ion reacts nrog ib OH– ion). Cov reacted acids thiab bases tuaj yeem muaj zog lossis tsis muaj zog. Nyob ntawm qhov xwm txheej ntawm cov kua qaub thiab lub hauv paus, muaj ntau ntau hom kev tsis sib haum xeeb raws li hauv qab no:
- Muaj zog acid-muaj zog puag cov tshuaj tiv thaiv
- Muaj zog acid-tsis muaj zog puag cov tshuaj tiv thaiv
- Tsis muaj kua qaub-tsis muaj zog puag cov tshuaj tiv thaiv
- Tsis muaj kua qaub-muaj zog puag cov tshuaj tiv thaiv
Ntawm cov plaub hom no, tsuas yog cov tshuaj tiv thaiv ntawm cov kua qaub muaj zog thiab cov hauv paus muaj zog muab cov tshuaj nruab nrab uas muaj pH=7. Lwm cov tshuaj tiv thaiv muab cov kev daws teeb meem nrog qhov sib txawv pH qhov tseem ceeb vim qhov txawv ntawm pH ntawm cov kua qaub / puag.
Qhov txawv ntawm Titration thiab Neutralization yog dab tsi?
Titration thiab neutralization yog cov ntsiab lus tseem ceeb hauv chemistry. Titration yog ib qho txheej txheem uas yuav tsum tau muaj cov cuab yeej tshwj xeeb, thiab nws ua raws li cov tshuaj tiv thaiv nruab nrab. Qhov sib txawv tseem ceeb ntawm titration thiab neutralization yog tias titration yog cov txheej txheem tshuaj ntsuam xyuas, qhov nruab nrab yog cov tshuaj tiv thaiv tshuaj.
Hauv qab infographic piv qhov sib txawv ntawm titration thiab neutralization hauv daim ntawv tabular.
Summary – Titration vs Neutralization
Titration thiab neutralization yog cov ntsiab lus tseem ceeb hauv chemistry. Titration yog ib qho txheej txheem uas yuav tsum tau muaj cov cuab yeej tshwj xeeb, thiab nws ua raws li cov tshuaj tiv thaiv nruab nrab. Qhov sib txawv tseem ceeb ntawm titration thiab neutralization yog tias titration yog ib qho kev tshuaj ntsuam xyuas, qhov nruab nrab yog cov tshuaj tiv thaiv tshuaj.
