A redox titration yog hom titration raws li a redox cov tshuaj tiv thaiv ntawm tus analytes thiab titrant. Ib qho piv txwv ntawm a redox titration yog kho cov tshuaj iodine nrog ib tug txo tus neeg sawv cev los tsim iodide siv cov hmoov txhuv nplej siab los pab txheeb xyuas qhov kawg.
Tsis tas li ntawd, redox titration yog dab tsi thiab nws ua haujlwm li cas?
Ib qho kev daws teeb meem ntawm kev paub paub, hu ua titrant, yog ntxiv rau kev daws teeb meem ntawm cov tshuaj ntsuam xyuas kom txog thaum txaus txaus ntxiv rau cov tshuaj tiv thaiv nrog tag nrho cov tshuaj ntsuam xyuas (qhov sib npaug taw tes). Yog hais tias cov tshuaj tiv thaiv ntawm tus titrant thiab tus analytes yog a txo-oxidation tshuaj tiv thaiv, tus txheej txheem hu ua a redox titration.
Tsis tas li ntawd, dab tsi yog txhais los ntawm cov tshuaj tiv thaiv redox? Ib oxidation-txo ( redox ) tshuaj tiv thaiv yog ib hom tshuaj tshuaj tiv thaiv uas muaj kev hloov ntawm electrons ntawm ob hom. Ib oxidation-txo cov tshuaj tiv thaiv yog ib yam tshuaj tshuaj tiv thaiv nyob rau hauv uas oxidation tooj ntawm ib tug molecule, atom, los yog ion hloov los ntawm kev txais los yog poob ib tug electron.
Kuj kom paub, dab tsi yog hom redox titration?
Hom Redox Titrations
- Bromometry siv bromine (Br2) kev.
- Cerimetry ntiav cerium (IV) ntsev.
- Dichrometry siv cov poov tshuaj dichromate.
- Iodometry siv iodine (I2).
- Permanganometry siv cov poov tshuaj permanganate.
Vim li cas peb thiaj siv redox titration?
Redox titration txiav txim siab qhov concentration ntawm cov tshuaj tsis paub (analyte) uas muaj oxidizing lossis txo tus neeg sawv cev. Tsis yog tag nrho titrations xav tau qhov ntsuas sab nraud. Qee cov titrants tuaj yeem ua haujlwm raws li lawv tus kheej ntsuas, xws li thaum poov tshuaj permanganate titrated tawm tsam ib qho tshuaj tsis muaj xim.

Koj txhais li cas los ntawm inertia ntawm kev coj?
Inertia ntawm kev taw qhia txhais tau tias yog qhov tsis muaj peev xwm ntawm lub cev lossis khoom siv los hloov nws txoj kev taw qhia ntawm nws tus kheej. Qhov ntawd yog sab nraud quab yuam yuav tsum tau hloov nws txoj kev taw qhia. Qhov no yog vim inertia ntawm kev coj
Vim li cas cov kua qaub nruab nrab tsim nyog hauv redox titration?
Muaj ob qhov laj thawj: Txhawm rau muab hydrogen ions rau cov tshuaj kom acidify nws. Qee qhov redox (xws li permanganate) muaj peev xwm oxidation zoo dua yog tias ua tau rau hauv qhov chaw acidic. Lub sulfate ion yog ib qho nyuaj ion rau oxidise nyob rau hauv ib txwm redox titrations, yog li koj tsis nquag tau byproducts
Vim li cas sulfuric acid siv hauv redox titration?
Sulfuric Acid (H2SO4) yog siv rau hauv cov txheej txheem redox titration vim nws muab H(+) ions tsim nyog rau cov tshuaj tiv thaiv kom tshwm sim sai dua thaum cov sulphate (-) ions NW nyuam qhuav tshwm sim thaum cov tshuaj tiv thaiv. Yog li ntawd, sulfuric acid yog ntxiv los ua kom cov kua qaub acidic
Koj txhais li cas los ntawm lo lus txhais?
Lub ntsiab lus txhais yog ib nqe lus ntawm lub ntsiab lus ntawm ib lo lus (ib lo lus, kab lus, lossis lwm yam cim). Cov lus txhais tau muab faib ua ob pawg loj, cov ntsiab lus tsis txaus ntseeg (uas sim muab lub ntsiab lus ntawm lub ntsiab lus) thiab cov ntsiab lus txuas ntxiv (uas sim sau cov khoom uas ib lo lus piav qhia)
Lub hom phiaj ntawm redox titration yog dab tsi?
Lub hom phiaj yog los ua ib qho titration ntawm cov tshuaj tiv thaiv redox kom pom qhov tsis paub qhov concentration ntawm cov tshuaj uas hloov electrons los ua cov tshuaj tshiab
