Txheej txheem cej luam. Lub burette yog lub ntsuas ntim ntim iav uas yog siv rau hauv kev tshuaj ntsuam chemistry rau qhov kev xa tawm ntawm cov kua, tshwj xeeb tshaj yog ntawm ib qho ntawm cov reagents hauv titration. Lub raj burette nqa cov qhab nia kawm tiav los ntawm qhov dispensed ntimntawm cov kua tuaj yeem txiav txim siab.

Dab tsi yog burette siv rau hauv titration?

Acid-base titrations yog siv txhawm rau txiav txim siab ntawm cov qauv ntawm cov kua qaub lossis cov hauv pausthiab tau nqa tawm siv cov khoom siv hu ua burette. Nws yog ib tug ntev, iav raj nrog ib tug kais ntawm qhov kawg uas yuav siv tau los ua tib zoo ntxiv tee dej rau ib qho kev sim tshuaj.

Yuav daws qhov twg hauv burette thaum titration?

Yuav kom ua tiav kev tshuaj ntsuam titrimetric, qauv kev daws teeb meemfeem ntau yog ntxiv los ntawm cov raj kawm tiav ntev hu ua burette. Cov txheej txheem ntawm kev ntxiv cov txheej txheem rau kev daws qhov tsis paub qhov concentration kom txog thaum cov tshuaj tiv thaiv tsuas yog ua tiav yog hu ua titration.

Puas yog titrant hauv lub burette?

Tus titrant ntxiv rau qhov ntsuas ntsuassiv lub raj xa dej kom raug hu ua lub burette (tseem sau buret; saib daim duab 12.1 "Cov khoom siv rau Titrations"). Lub burette muaj cov cim los txiav txim siab npaum li cas ntim cov tshuaj tau ntxiv rau qhov ntsuas.

Titration hauv titration yog dab tsi?

A titration txhais tau tias yog 'txheej txheem ntawm kev txiav txim siabkom muaj nuj nqis ntawm cov khoom A los ntawm kev ntsuas qhov nce ntxiv ntawm cov khoom B, lub titrant, uas nws reacts kom txog rau thaum cov tshuaj sib npaug sib npaug (qhov sib npaug taw tes)'.
