Hom Titrations • Acid-base titrations , nyob rau hauv uas ib tug acidic los yog yooj yim titrant reacts nrog analyte uas yog lub hauv paus los yog ib tug acid. Dej nag titrations , nyob rau hauv uas lub analyte thiab titrant react rau daim ntawv aprecipitate. • Redox titrations , qhov twg titrant isan oxidizing lossis txo tus neeg sawv cev.
Ua li no, peb muaj pes tsawg hom titration?
Plaub Basic Hom ntawm Acid-Base Titrations . Table [Kev ua lej yuam kev] qhia plaub hom kev tiv thaiv , thiab koj Nco ntsoov tias titrant (cov khoom sib xyaw hauv lub burret uas ntxiv rau qhov ntsuas) yeej ib txwm muaj zog, thaum lub ntsuas ntsuas ua tau yuav muaj zog los yog qaug zog. Nyob ntawd yog ob qho laj thawj rau qhov no.
Lub hom phiaj ntawm titration hauv chemistry yog dab tsi? Qhov concentration ntawm ib qho kev daws teeb meem tuaj yeem txiav txim siab titrating nws nrog ib tug ntim ntawm tus qauv acid tov (ntawm paub concentration) yuav tsum tau neutralize nws. Cov lub hom phiaj ntawm titration yog qhov kuaj pom ntawm qhov sib npaug, qhov taw tes ntawm cov tshuaj sib npaug ntawm cov reactants tau sib xyaw.
Ua li no, txhais li cas los ntawm titration?
A titration yog ib tug txheej txheem uas ib tug tov ntawm paub concentration yog siv los txiav txim siab concentration ntawm anunknown tov. Feem ntau, titrant (qhov paub daws) yog ntxiv los ntawm buret mus rau qhov paub ntau npaum li cas ntawm cov tshuaj ntsuam xyuas (qhov tsis paub daws teeb meem) kom txog thaum cov tshuaj tiv thaiv tiav.
Dab tsi yog hom redox titration?
Redox Cov tshuaj tiv thaiv yog sib txuam ua ke: yog tias ib hom kab mob oxidized hauv a tshuaj tiv thaiv , lwm tus yuav tsum tau txo. Khaws qhov no hauv siab thaum peb saib tsib lub ntsiab hom redox Cov tshuaj tiv thaiv: kev sib xyaw ua ke, decomposition, hloov chaw, combustion, thiab disproportion.

Dab tsi yog qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
Dab tsi yog txheej txheem ntuj tsim ua rau ib hom pob zeb hloov mus rau lwm hom?
Peb hom pob zeb tseem ceeb yog igneous, metamorphic thiab sedimentary. Peb txheej txheem uas hloov ib lub pob zeb mus rau lwm qhov yog crystallization, metamorphism, thiab yaig thiab sedimentation. Txhua lub pob zeb tuaj yeem hloov mus rau lwm lub pob zeb los ntawm kev dhau los ntawm ib lossis ntau dua ntawm cov txheej txheem no. Qhov no tsim lub voj voog pob zeb
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
Dab tsi yog junk DNA thiab nws lub hom phiaj yog dab tsi?
Hauv cov noob caj noob ces, lo lus khib nyiab DNA hais txog thaj tsam ntawm DNA uas tsis yog coding. Qee qhov DNA noncoding no yog siv los tsim cov khoom tsis yog RNA xws li hloov RNA, tswj RNA thiab ribosomal RNA
Dab tsi yog qhov txawv ntawm N hom semiconductor thiab P hom semiconductor?
Hauv N-hom semiconductor, cov khoom siv hluav taws xob feem ntau yog cov neeg nqa khoom thiab qhov yog cov neeg nqa khoom tsawg. Hauv P-hom semiconductor, qhov yog feem ntau cov neeg nqa khoom thiab cov khoom siv hluav taws xob yog cov neeg tsawg. Nws muaj qhov loj dua electron concentration thiab tsawg lub qhov concentration. Nws muaj qhov loj dua qhov concentration thiab tsawg dua electron concentration
