Qhov sib txawv tseem ceeb ntawm acidimetry thiab alkalimetry yog acidimetry yog qhov ntsuas ntawm lub zog ntawm cov kua qaub, whereas alkalimetry yog ntsuas lub zog ntawm alkaline tebchaw.
Acidimetry thiab alkalimetry yog ob hom kev ntsuas ntsuas ntsuas qhov twg cov tshuaj tiv thaiv tseem ceeb ntawm kev tshuaj xyuas yog hom tshuaj tiv thaiv neutralization.
Acidimetry yog dab tsi?
Acidimetry yog cov txheej txheem tshwj xeeb uas siv los txiav txim siab lub zog ntawm cov kua qaub. Peb tuaj yeem siv cov txheej txheem no hauv cov kua qaub-piv titration los txiav txim siab cov ntsiab lus ntawm cov ntsiab lus los yog cov khoom alkaline. Txawm li cas los xij, peb yuav tsum tau siv cov tshuaj kua qaub rau qhov kev txiav txim siab no. Nws muaj kev cuam tshuam neutralization. Hom kev tshuaj tiv thaiv no muaj txiaj ntsig zoo hauv cov txheej txheem ntsuas ntsuas.
Nyob hauv acidimetry, tus qauv acid peb siv yuav tsum muaj ib tug paub concentration; txwv tsis pub, peb tsis tuaj yeem txiav txim siab qhov concentration ntawm lub hauv paus. Txij li yuav luag txhua cov kua qaub thiab cov hauv paus peb feem ntau siv hauv cov txheej txheem acid-base titration tsis muaj xim, peb yuav tsum siv qhov ntsuas uas pab txiav txim qhov kawg ntawm qhov titration.
Tom qab ua cov kua qaub-puag titration, peb tuaj yeem siv cov kev sib raug zoo hauv qab no rau kev txiav txim siab ntawm lub hauv paus.
C1V1=C2V2
Qhov twg C1 yog qhov concentration ntawm tus qauv acid, V1 yog qhov ntim ntawm cov kua qaub nrog cov qauv tshuaj ntsuam xyuas, C2 yog qhov tsis paub qhov concentration ntawm lub hauv paus (uas peb yuav pom), thiab V2 yog qhov ntim ntawm cov qauv tshuaj ntsuam xyuas (base).
Alkalimetry yog dab tsi?
Alkalimetry yog cov txheej txheem tshwj xeeb uas peb tuaj yeem siv los txiav txim siab lub zog ntawm lub hauv paus lossis cov alkaline compound. Hauv cov txheej txheem no, peb tuaj yeem txiav txim siab qhov concentration ntawm ib qho yooj yim lossis alkaline tshuaj yog tias peb siv cov tshuaj tiv thaiv hauv cov txheej txheem acid-base titration. Nws koom nrog kev tawm tsam nruab nrab.
Daim duab 01: Siv lub ntsuas phenolphthalein los txiav txim qhov kawg ntawm cov kua qaub-base titration muab cov xim liab
Nyob rau hauv alkalimetry, tus qauv puag peb siv yuav tsum muaj ib tug paub concentration; Yog tias tsis yog, peb tsis tuaj yeem txiav txim siab qhov concentration ntawm cov kua qaub. Txij li yuav luag tag nrho cov kua qaub thiab cov hauv paus peb feem ntau siv hauv cov txheej txheem acid-base titration tsis muaj xim, peb yuav tsum siv qhov ntsuas uas pab txiav txim qhov kawg ntawm qhov titration.
Qhov txawv ntawm Acidimetry thiab Alkalimetry yog dab tsi?
Nyob rau hauv analytical chemistry, nws yog ib qho tseem ceeb heev kom paub lub zog ntawm acids thiab bases peb siv nyob rau hauv ib qho kev tsom xam. Acidimetry thiab alkalimetry muaj txiaj ntsig los txiav txim siab qhov muaj zog no. Qhov sib txawv tseem ceeb ntawm acidimetry thiab alkalimetry yog acidimetry yog qhov ntsuas ntawm lub zog ntawm acids, whereas alkalimetry yog ntsuas lub zog ntawm alkaline tebchaw. Tsis tas li ntawd, acidimetry ntsuas qhov nyiam ntawm cov kua qaub rau kev sib cais, tsim protons thiab anion, thaum alkalimetry ntsuas qhov nyiam ntawm lub hauv paus kom txais cov protons los ntawm lwm hom tshuaj.
Tsis tas li ntawd, cov hauv qab no qhia txog qhov sib txawv ntawm acidimetry thiab alkalimetry hauv daim ntawv tabular.
Summary – Acidimetry vs Alkalimetry
Nyob rau hauv analytical chemistry, nws yog ib qho tseem ceeb heev kom paub lub zog ntawm acids thiab bases peb siv nyob rau hauv ib qho kev tsom xam. Acidimetry thiab alkalimetry yog ob hom kev soj ntsuam volumetric qhov twg cov tshuaj tiv thaiv tseem ceeb ntawm kev tsom xam yog ib hom tshuaj tiv thaiv neutralization. Qhov sib txawv tseem ceeb ntawm acidimetry thiab alkalimetry yog acidimetry yog qhov ntsuas ntawm lub zog ntawm cov kua qaub, whereas alkalimetry yog ntsuas lub zog ntawm alkaline tebchaw.
