Ib rov qab titration yog siv thaum lub molar concentration ntawm ib qho reactant ntau tshaj yog paub, tab sis qhov xav tau muaj los txiav txim siab lub zog los yog concentration ntawm ib qho tshuaj ntsuam xyuas. Rov qab titration feem ntau yog siv rau hauv acid-base titrations: Thaum cov kua qaub los yog (feem ntau) puag yog ib qho ntsev insoluble (piv txwv li, calcium carbonate)
Vim li cas peb thiaj siv rov qab titration?
A rov qab titration yog siv tau yog qhov kawg ntawm qhov rov qab titration yooj yim dua los txheeb xyuas dua qhov kawg ntawm qhov qub titration, zoo li nag lossis daus. Rov qab titrations kuj tseem muaj txiaj ntsig yog tias cov tshuaj tiv thaiv ntawm cov tshuaj ntsuam xyuas thiab cov titrant qeeb heev, los yog thaum cov tshuaj ntsuam xyuas nyob rau hauv cov khoom tsis-soluble.
Dab tsi yog qhov rov qab titration siv?
Rov qab titrations feem ntau yog siv rau hauv cov xwm txheej hauv qab no:
- yog tias tus ntsuas tsis hloov pauv (piv txwv li, NH 3) lossis ntsev tsis txaus (piv txwv li, Li2CO 3)
- yog tias cov tshuaj tiv thaiv ntawm cov tshuaj ntsuam A thiab titrant T qeeb dhau rau kev siv titration ncaj qha.
Puas yog piv txwv ntawm rov qab titration?
Rov qab titration ua haujlwm raws li hauv qab no (nrog ib qho piv txwv): 1: Cov tshuaj los yog cov tshuaj tsis paub meej (4 gm ntawm cov kab mob sib kis, CaCO3) yog ua kom hnov mob nrog paub ntim thiab concentration. ntawm intermediate reactant tov(200 ml, 0.5N HCl). Cov tshuaj tiv thaiv dhau los ntawm qhov sib npaug.
Vim li cas EDTA siv nyob rau hauv rov qab titration?
Rov qab titration: paub ntau dhau ntawm cov qauv kev daws teeb meem EDTA ntxiv rau cov tshuaj uas muaj cov tshuaj ntsuam xyuas. … Cov txheej txheem no yog siv tau rau kev txiav txim siab cations uas tsim cov complexes ruaj khov nrog EDTA thiab rau qhov uas tsis muaj qhov taw qhia zoo.
