Kev Ntsuas Volumetric
- Npaj ib qho kev daws teeb meem los ntawm cov qauv ntsuas kom raug rau +/- 0.0001 g ntawm cov khoom los ua soj ntsuam .
- Xaiv ib yam khoom uas yuav hnov mob sai thiab ua tiav nrog cov tshuaj ntsuam xyuas thiab npaj cov txheej txheem kev daws teeb meem ntawm cov khoom no.
- Muab cov txheej txheem tov rau hauv ib lub buret thiab ntxiv nws maj mam mus rau qhov tsis paub.
Tsis tas li lo lus nug yog, plaub txoj hauv kev ntawm kev tsom xam volumetric yog dab tsi?
Qhov tseeb qhov hnyav ntawm cov khoom yog tus yuam sij rau qhov tseeb. Indicators feem ntau xav tau los tsim qhov kawg-point hauv a kev tsom xam volumetric . Acid-Base titrations, Redox titrations thiab Complexometric titrations yog cov cov txheej txheem loj hauv kev tsom xam volumetric.
Ib tug kuj yuav nug, puas yog qhov ntsuas volumetric tib yam li titration? Titration yog hom kev tsom xam volumetric . Tag nrho kev tsom xam volumetric txoj kev koom nrog titrations . Tab sis lub sij hawm titration yog siv thaum a kev tsom xam volumetric yog ua los txiav txim siab qhov concentration ntawm ib qho tsis paub tivthaiv nyob rau hauv ib qho kev daws whereas lub sij hawm kev tsom xam volumetric yog siv los txiav txim ob peb lwm yam thiab.
Hauv qhov no, qhov kev ntsuas volumetric siv rau dab tsi?
Nws yog feem ntau siv los txiav txim qhov tsis paub qhov concentration ntawm ib tug paub reactant. Volumetric tsom xam feem ntau hu ua titration, ib qho kev sim hauv cov txheej txheem uas ib yam khoom uas paub txog concentration thiab ntim yog siv kom hnov mob nrog lwm yam khoom uas tsis paub concentration.
Dab tsi yog qhov sib txawv ntawm kev ntsuas volumetric?
Hom Titration. Muaj ntau ntau hom titration thaum xav txog cov hom phiaj thiab cov txheej txheem. Txawm li cas los xij, feem ntau hom titration hauv quantitative tshuaj Kev tsom xam yog redox titration thiab acid-base titration.

Koj txhais li cas los ntawm phylogenetic tsom xam?
Phylogeny hais txog evolutionary keeb kwm ntawm hom. Phylogenetics yog kev kawm ntawm phylogenies - uas yog, kev kawm txog kev sib raug zoo ntawm cov tsiaj. Hauv kev tshuaj xyuas molecular phylogenetic, qhov sib lawv liag ntawm cov noob lossis cov protein tuaj yeem siv los ntsuas qhov kev sib raug zoo ntawm cov tsiaj
Dab tsi yog cov kev siv ntawm gravimetric tsom xam?
Kev siv Gravimetric tsom xam. Gravimetric tsom xam yog cov txheej txheem uas yog siv los ntsuas tus nqi ntawm cov tshuaj analytes lossis theej cov ion raug tshuaj xyuas. Cov txheej txheem siv qhov loj ntawm cov tshuaj ntsuam xyuas los ua tus nqi. Tsis tas li ntawd, cov txheej txheem yog nyob ntawm qhov loj ntawm ob lub tebchaw uas muaj cov tshuaj ntsuam xyuas
Yuav ua li cas yog classical txoj kev tsom xam?
Classical tsom xam, kuj hu ua ntub chemicalanalysis, muaj cov txheej txheem analytical uas siv nomechanical lossis hluav taws xob cov cuab yeej uas tsis yog qhov sib npaug. Cov txheej txheem feem ntau yog nyob ntawm cov tshuaj tiv thaiv ntawm cov khoom siv tshuaj ntsuam xyuas (cov tshuaj ntsuam xyuas) thiab cov reagent uas tau ntxiv rau
Yuav ua li cas koj xam lub sij hawm nws yuav siv sij hawm mus ncig teb chaws?
Kwv yees seb koj yuav mus sai npaum li cas ntawm koj qhov kev mus ncig. Tom qab ntawd, faib koj qhov kev ncua deb ntawm koj qhov nrawm. Qhov no yuav muab rau koj anestimation ntawm koj lub sijhawm mus ncig. Piv txwv li, yog tias koj mus ncig yog 240 mais thiab koj yuav tsav 40 mais ib teev, koj lub sijhawm yuav yog 240/40 = 6hours
Yuav ua li cas koj xam lub sij hawm nws yuav siv ib yam khoom los poob?
Ntsuas qhov deb ntawm qhov khoom yuav poob hauv ko taw nrog tus pas ntsuas lossis ntsuas daim kab xev. Faib qhov kev ncua deb los ntawm 16. Piv txwv li, yog tias cov khoom yuav poob 128 ko taw, faib 128 los ntawm 16 kom tau 8. Xam cov square root ntawm cov kauj ruam 2 los nrhiav lub sij hawm nws yuav siv cov khoom poob hauv vib nas this
