Friedrich Kohlrausch txuas ntxiv txhim kho conductometry nyob rau xyoo 1860 thaum nws siv alternating tam sim no rau dej, acids, thiab lwm yam kev daws teeb meem. Nws kuj tseem nyob ib puag ncig lub sijhawm no thaum Willis Whitney, uas tau kawm txog kev sib cuam tshuam ntawm sulfuric acid thiab chromium sulfate complexes, pom thawj qhov kawg ntawm conductometric.

Leej twg nrhiav tau titration?

Nyob rau hauv lub 18th xyoo pua, Francois Antoine Henri Descroizilles1tsim thawj buret. Cov txheej txheem tau tsim ntxiv los ntawm Karl Friedrich Mohr, uas, xyoo 1855, tau sau thawj phau ntawv hais txog titration, hu ua "Kev Qhia Phau Ntawv ntawm Titration Methods hauv Kev Tshawb Fawb Chemistry."

Lub hauv paus ntsiab lus tom qab conductometric titration yog dab tsi?

Lub hauv paus ntsiab lus ntawm txoj kev xav ntawm conductometric titrations hais tias rau cov dilutions uas yog infinite, ions ua nws tus kheej thiab hauv cov txheej txheem pab txhawb rau kev coj ua ntawm kev daws teeb meem. Lub hauv paus ntsiab lus tom qab qhov kev xav no hais tias anions thiab cations muaj qhov sib txawv ntawm kev coj ua.

Leej twg nrhiav tau acid puag titration?

In 1828, tus Fabkis chemist Joseph Louis Gay-Lussac thawj zaug siv titre ua lus qhia (titrer), lub ntsiab lus "kom txiav txim siab qhov concentration ntawm cov khoom hauv ib qho qauv". Volumetric tsom xam tau pib nyob rau hauv lig 18th-xyoo pua Fabkis.

Vim li cas thiaj siv conductometric titration?

"Conductometric titration yog ib homtitration nyob rau hauv uas cov electrolytic conductivity ntawm cov tshuaj tiv thaiv sib tov yog tsis tu ncua saib raws li ib tug reactant ntxiv. " Nyob rau hauv no titration conductometer yog siv rau ntsuas conductance. … Yog vim li cas nws thiaj haum rau titration ntawm cov xim daws teeb meem.
