Tom qab txhua qhov sib ntxiv, ntxuav ob sab ntawm lub hwj nrog dej distilled kom paub meej tias tsis muaj lub hauv paus ntawm lub khob. Nco ntsoov qhov kev hloov ntawm cov xim tshwm sim nrog qhov sib ntxiv ntawm tsuas yog ib qho poob lossis tsawg dua ntawm titrant.
Dab tsi yog siv los ntxuav ob sab ntawm lub khob thaum lub sij hawm titration?
Thaum ua titrations nrog cov tshuaj aqueous, tsuas yog dej distilled yog siv los yaug lub khob conical thiaj li tsis txhob tawm hauv cov tshuaj seem hauv lub …
Vim li cas cov dej distilled siv los ntxuav hauv lub khob conical thaum lub sij hawm titration?
Thaum koj tau txais koj cov kua qaub ntawm qhov tsis paub qhov concentration hauv lub khob ntim dej, nws yog lub sijhawm los teeb tsa lub burette nrog koj cov alkali ntawm kev paub txog concentration.… Raws li cov pipette, lub burette yuav tsum tau muab yaug nrog dej distilled raws li cov tshuaj nws yog muab ntim nrog kom tsis txhob muaj teeb meem paug
Vim li cas lub burette thiaj yaug nrog kua qaub ua ntej titration?
Titration yog ib txoj kev tshuaj ntsuam xyuas, uas tso cai rau kwv yees qhov concentration ntawm cov tshuaj muab. Yog li, koj yuav tsum yaug cov burette nrog cov tshuaj uas yuav tsum tau sau rau hauv nws, vim cov dej distilled hloov qhov concentration ntawm cov tshuaj thawj zaug.
Vim li cas titration fwj yuav tsum tsis txhob muab yaug?
Yog tias nws tau yaug nrog cov tshuaj raws li kev sim uas tsis zoo- uas yuav cuam tshuam rau tus naj npawb ntawm cov molecules ntawm reactant hauv lub khob. … Ib yam li ntawd, lub burette uas koj siv los ntxiv koj cov qauv kev daws teeb meem thaum lub sij hawm titration yuav tsum tau muab yaug nrog cov txheej txheem daws kom tsis txhob diluting nws.
