Nyob rau hauv ib qho iodometric titration, a hmoov txhuv nplej siab yog siv los ua qhov taw qhia vim nws tuaj yeem nqus tau cov I2 uas tso tawm.
Qhov ntsuas twg yog siv hauv iodometric titration?
Qhov taw qhia uas feem ntau yog xaiv rau titrations uas muaj iodine (triiodide) yog starch. Cov hmoov txhuv nplej siab tsim cov xim xiav tsaus nrog iodine. Qhov kawg taw tes hauv iodimetry sib haum mus rau qhov hloov pauv sai sai rau xiav. Ib yam li qhov kawg taw tes hauv iodometry sib raug rau qhov poob ntawm xiav xim vim qhov nyuaj.
Lub luag haujlwm ntawm KI hauv iodometric titration yog dab tsi?
KI, lossis potassium iodide, yog siv hauv iodometric titration vim cov iodide yuav raug oxidized rau iodine nyob rau hauv lub xub ntiag ntawm ib tug oxidizing agent.
Titrant hauv iodometry yog dab tsi?
Lo lus "iodometry" piav qhia txog hom titration uas siv tus qauv sodium thiosulfate tovraws li titrant, ib qho ntawm ob peb tus neeg ua haujlwm ruaj khov uas oxidisation ntawm huab cua muaj kev txhawj xeeb. … Nyob rau hauv lub xub ntiag ntawm iodine, thiosulphate ions oxidise ntau npaum li cas rau tetrathionate ions.
Vim li cas iodometric titration hu ua indirect titration?
Cov iodine tsim hauv cov tshuaj tiv thaiv tuaj yeem raug titrated los ntawm cov txheej txheem sodium thiosulfate tov. Hom indirect titration no tau muab lub npe dav dav ntawm iodometry. … Yog li ntawd, thaum xiav-dubCov xim ploj, cov iodine tau raug txo kom iodide ion.
