Nws yog ib qho tseem ceeb txhais tau tias tus cwj pwm ntawm cov kua qaub. Tsis siv qhov taw qhia; hloov lub peev xwm ntsuas thoob plaws qhov ntsuas, feem ntau yog cov tshuaj electrolyte . … Yog li lub potentiometric titration suav nrog kev ntsuas ntawm Ecell nrog ntxiv ntawm titrant.
ntsuas electrode hauv potentiometry yog dab tsi?
Hauv potentiometry, ob lub electrodes feem ntau hu ua qhov taw qhia electrode thiab siv electrode. Qhov taw qhia electrode muaj qee tus yam ntxwv uas tso cai rau nws xaiv los teb cov kev hloov pauv hauv cov haujlwm ntawm ntsuas ntsuas.
Dab tsi yog qhov taw qhia ntawm qhov kawg ntawm qhov kev sib tw potentiometric?
Acid-Base Titration: Hom potentiometric titration no yog siv los txiav txim siab qhov concentration ntawm cov kua qaub / hauv paus los ntawm kev ua kom tsis zoo los ntawm kev siv cov txheej txheem kev daws teeb meem ntawm lub hauv paus / acid uas nws cov concentration paub. … Qhov kawg ntawm qhov titration no tau sau tseg thaum qhov sib ntxiv ntawm cov titrant tsis tsim cov dej nag ntxiv lawm.
Puas pH ntsuas siv tau rau potentiometric titration?
Nyob rau hauv potentiometric acid-base titration, qhov taw qhia tsis tsim nyog. Lub pH meter yog siv los ntsuas pH raws li lub hauv paus tau ntxiv me me ntxiv (hu ua aliquots) rau cov kua qaub. Ib daim duab yog ua nrog pH raws txoj kab ntsug thiab ntim ntawm lub hauv paus ntxiv raws kab kab rov tav.
Vim li cas HCl tsis siv hauv potentiometric titration?
Hydrochloric acid (HCl) feem ntau tsis siv rau hauv cov txheej txheem titration vim nws cuam tshuam nrog cov ntsuas poov tshuaj permanganate (KMnO 4) uas yog siv hauv cov txheej txheem. Nws reacts nrog KMnO4 cov tshuaj thiab tau oxidized uas ntxiv ua rau lub liberation ntawm chlorine gas.
