1 、 Muaj peb yam hauv tag nrho.
(1) Kev ntsuas ntsuas nrog cov khoom hnyav hnyav thiab cov hlab ntsha ntsuas cov tshuaj ntim
(2) Cov kev daws teeb meem muaj peev xwm ntawm titration
(3) Qhov taw qhia kom raug txiav txim siab qhov kawg ntawm theoretical.
- Classification ntawm titration tsom xam.
Muaj plaub pawg, acid-base titration, complexometric titration, redox titration, thiab nag lossis daus titration.
Txoj kev acid-base titration yog ib txoj kev tsom xam titration raws li kev hloov pauv ntawm cov tshuaj tiv thaiv proton siv cov kua qaub thiab lub hauv paus hauv dej.
Nws tuaj yeem siv los txiav txim siab acid, puag thiab amphoteric tshuaj. Nws yog ib txoj hauv kev los soj ntsuam lub peev xwm siv cov tshuaj tiv thaiv acid-base. Cov kua qaub tuaj yeem siv los ua titrant los txiav txim siab lub hauv paus, thiab lub hauv paus tuaj yeem siv los ua titrant los txiav txim siab cov kua qaub, uas yog ib qho kev tshuaj ntsuam xyuas ntau yam. Cov kua qaub uas siv ntau tshaj plaws yog hydrochloric acid, qee zaum nrog nitric acid thiab sulfuric acid. Cov khoom siv uas lawv tau ntsuas yog sodium carbonate.
Txoj kev complexometric titration yog ib txoj kev tsom xam titration raws li cov tshuaj tiv thaiv complexation. Nws tsuas yog siv ammonia carboxylate complexing tus neeg sawv cev ua titrant. Cov amino carboxylate complexing agents muaj zog complexing muaj peev xwm rau ntau hlau.
Redox titration yog ib txoj kev tsom xam titration raws li kev hloov hluav taws xob ntawm cov oxidant thiab tus neeg sawv cev txo qis hauv cov tshuaj. Thiab acid-base titration thiab ligand titration piv redox titration daim ntawv thov yog dav heev, nws yuav siv tau tsis tsuas inorganic tsom xam, thiab yuav tau lug siv rau cov organic tsom xam, muaj ib tug xov tooj ntawm oxidizing los yog txo cov organic compound yuav siv tau ib tug redox lub titration. txoj kev tau siv rau kev ntsuas.
nag lossis daus titration yog ib txoj kev tsom xam titration raws li nag lossis daus cov tshuaj tiv thaiv.
Yog tias koj muaj lus nug, tsis txhob yig tiv tauj nrog WUBOLAB, lub Laboratory glassware chaw tsim tshuaj paus.
