Acid Base Titration Qhov Chaw ntawm Kev Txhim Kho yuam kev
- Xyuas cov calibration ntawm cov tshuav nyiaj li cas.
- Txheeb xyuas qhov ntawd cov thawj tus qauv yog kom qhuav.
- Pom tseeb cov precision ntawm cov khob iav.
- Siv qhov ntau txaus ntawm kev tshuaj ntsuam thiab titrant.
- Paub cov cov kev txwv ntawm cov khoom siv.
Kuj paub, koj yuav ua li cas kom ntseeg tau qhov tseeb hauv kev sim ua titration?
Cov ntsiab lus hauv txheej no (9)
- Meniscus ntawm qhov muag qib. Txhawm rau zam kev ua parallax yuam kev.
- Pobzeb dawb. Kom pom qhov kawg pom meej dua.
- Tshem cov funnel ua ntej titrating. Ua kom cov vol ua rau lub npe me dua.
- Dropwise ntxiv.
- Tsis muaj npuas hauv pipette & burette ntawm qhov taub.
- Swirling thaum titration.
- Ob peb tee ntawm qhov taw qhia.
- Rov ua dua cov titration.
Tsis tas li ntawd, dab tsi tuaj yeem cuam tshuam rau cov txiaj ntsig cov ntsiab lus? Ob peb yam ua tau ua kom yuam kev hauv titration kev tshawb pom, suav nrog kev nyeem tsis raug tag, ua yuam kev qhov tseem ceeb lossis cov txheej txheem tsis raug. Kev saib xyuas yuav tsum tau ua raws li qhov kev daws teeb meem ntawm qhov paub paub tau nthuav tawm rau hauv qhov ntim tshwj xeeb ntawm qhov tsis paub los ntawm cov iav tsom iav xws li burette lossis pipette.
Ib yam li ib tus tuaj yeem nug, yuav ua li cas thiaj tuaj yeem nyeem tau qhov tseeb tshaj plaws hauv cov ntsiab lus?
Electrode Calibration pH electrodes yuav tsum tau ntsuas txhua hnub kom ua tiav qhov nyeem tau raug tshaj plaws . Ob txoj hauv kev yog feem ntau txaus, thaum siv qhov tsis tsim nyog. Qhov tsis tsim nyog yuav tsum raug xaiv raws li ntsuas ntau yam yuav rau yuav tsum tau los ntawm titration.
Yuav ua li cas titration yuam kev raug txo?
Cov kauj ruam rau txo qhov yuam kev Cov kab mob sib kis los yog dilution Cov raj dej yuav tsum tau yaug nrog DI dej nkaus xwb. Pipette thiab burette yuav tsum tau yaug 3 zaug nrog DI dej, tom qab ntawd 3 zaug nrog cov tshuaj lawv yuav ntsuas thiab hloov pauv. Tus nqi ntawm qhov ntsuas Qhov no yuav tsum zoo ib yam thoob plaws txhua qhov cov ntsiab lus ; 3 tee yog ib txwm.
