Titrimetry yog hais txog ib pawg ntawm cov txheej txheem ntawm kev tshuaj xyuas ntau yam uas tus kws tshuaj ntsuam xyuas tau txiav txim siab raws li nws cov tshuaj tiv thaiv stoichiometric nrog cov reagent ntawm tsim kom muaj concentration qhia rau tus qauv maj mamkom txog rau thaum cov tshuaj ntsuam xyuas yog noj quantitatively.
Titration hauv chemistry yooj yim txhais yog dab tsi?
titration, txheej txheem ntawm kev tshuaj xyuas tshuaj nyob rau hauv uas qhov ntau ntawm qee cov qauv ntawm cov qauv txiav txim los ntawm kev ntxiv rau cov qauv ntsuas qhov paub meej ntau ntawm lwm yam khoom uas xav tau cov ntsiab lus teb rau hauv qhov tseeb, paub qhov sib npaug.
Lub hauv paus ntsiab lus ntawm kev txiav txim siab yog dab tsi?
Lub hauv paus ntsiab lus ntawm kev titration yog cov hauv qab no: Ib qho tshuaj - yog li hu ua titrant lossis standard solution - yog ntxiv rau cov qauv los soj ntsuam Lub titrant muaj ib tug paub concentration ntawm ib tug tshuaj uas reacts nrog cov tshuaj yuav tsum tau txiav txim. Lub titrant yog ntxiv los ntawm kev siv lub burette.
Titrimetry siv rau dab tsi?
1 Titration. Titration, tseem hu ua titrimetry, yog ib qho kev sim tshuaj ntsuam xyuas ntau npaum li cas uas yog siv los txiav txim siab qhov tsis paub txog qhov txheeb xyuas qhov txheeb xyuas (Medwick thiab Kirschner, 2010). Txij li thaum ntsuas ntim ua lub luag haujlwm tseem ceeb hauv titration, nws tseem hu ua kev ntsuas ntsuas.
gravimetry thiab titrimetry yog dab tsi?
Qhov sib txawv tseem ceeb ntawm kev soj ntsuam gravimetric thiab titrimetric yog qhov kev soj ntsuam gravimetric ntsuas qhov ntau ntawm tus ntsuas ntsuas qhov hnyav, qhov kev tshuaj ntsuam titrimetric ntsuas qhov ntau ntawm kev ntsuas siv ntim. … Yog hais tias peb ntsuas qhov ntim, peb hu nws "volumetric tsom xam" lossis "titrimetric tsom xam ".

Dab tsi yog qhov tshwm sim hauv chemistry?
Cov reactivity series ntawm hlau yog daim ntawv teev cov hlau kom txo qis reactivity. Feem ntau, qhov ntau reactive ib hlau yog: qhov ntau vigorously nws reacts nrog lwm yam tshuaj. yooj yim dua nws poob electrons los tsim cov ions zoo (cations) Dab tsi yog qhov reactivity series piav nrog piv txwv?
Nyob hauv chemistry dab tsi yog tus neeg sawv cev chelate?
Chelating agents yog organic compounds muaj peev xwm txuas ua ke hlau ions los tsim cov nplhaib zoo li cov qauv hu ua chelates. Los ntawm: Phau ntawv ntawm Toxicology ntawm Kev Ua Tsov Rog Tshuaj Tshuaj, 2009 . Yuav ua li cas yog tus neeg sawv cev chelate?
Dab tsi yog absorbent hauv chemistry?
Nyob rau hauv chemistry, kev nqus yog ib qho lub cev lossis tshuaj phenomenon lossis txheej txheem uas atoms, molecules lossis ions nkag mus rau qee theem - kua lossis khoom siv. … Lub absorbent faib cov khoom uas nws ntes thoob plaws tag nrho thiab adsorbent tsuas yog faib nws mus rau saum npoo .
Lub hauv paus hauv chemistry yog dab tsi?
base, hauv chemistry, txhua yam khoom uas nyob rau hauv cov kua dej yog nplua rau qhov kov, saj iab, hloov xim ntawm cov ntsuas(piv txwv li, tig liab litmus ntawv xiav), reacts nrog acids los tsim cov ntsev, thiab txhawb qee cov tshuaj tiv thaiv kab mob (base catalysis) .
Puas yog inorganic chemistry tib yam li cov chemistry?
Tus Tswv Cuab. Yes it is same. General chemistry=inorganic chemistry and thats all that schools as for . Dab tsi yog qhov txawv ntawm inorganic chemistry thiab general chemistry? Organic, Inorganic thiab Organometallic feem ntau, cov tshuaj lom neeg muaj feem xyuam nrog cov tebchaw uas muaj cov pa roj carbon, thiab inorganic chemistry suav nrog cov tebchaw uas tsis muaj carbon atoms .
