Qhov sib txawv tseem ceeb ntawm cov tshuaj hauv Tshuag thiab cov qauv kev daws teeb meem yog cov tshuaj hauv Tshuag yog cov tshuaj muaj zog heev, qhov kev daws teeb meem yog kev daws teeb meem uas muaj kev paub meej meej.
Cov khoom lag luam thiab cov qauv kev daws teeb meem yog cov ntsiab lus cuam tshuam vim tias cov qauv kev daws teeb meem feem ntau tuaj raws li cov kev daws teeb meem. Qhov no txhais tau tias, qee zaum peb tuaj yeem siv cov ntsiab lus sib hloov. Muaj ob hom kev daws teeb meem raws li cov qauv thawj thiab cov qauv thib ob. Cov kev daws teeb meem tuaj yeem yog thawj lossis tus qauv thib ob, lossis nws tuaj yeem ua lwm yam tshuaj reagent ib yam nkaus.
Txoj kev daws teeb meem yog dab tsi?
A cov tshuaj Tshuag yog cov tshuaj muaj zog heev. Cov kev daws teeb meem no muaj txiaj ntsig zoo vim tias peb tuaj yeem dilute ib feem ntawm cov tshuaj hauv Tshuag kom tau txais qhov xav tau concentration. Cov kev daws teeb meem no yog qhov tseem ceeb hauv kev txuag lub sijhawm npaj ntawm cov tshuaj reagents. Tsis tas li ntawd, nws pab peb khaws cov khoom. Qhov no txhais tau hais tias siv cov tshuaj hauv Tshuag kom tau txais cov tshuaj tsis tshua muaj siab tsuas yog siv ib feem ntawm cov khoom lag luam thiab cov kuab tshuaj uas xav tau rau cov txheej txheem dilution. Nws tseem yog ib qho tseem ceeb los txo qhov chaw cia vim tias peb tsis tas yuav npaj cov kev daws teeb meem uas siv cov reagents sib txawv ntawm cov txheej txheem sophisticated; peb tsuas yog yuav tsum tau dilute lub Tshuag tov. Tsis tas li ntawd, nws txhim kho qhov tseeb ntawm kev sim.
Ib qho kev daws teeb meem yog lub ntim loj ntawm cov tshuaj reagent. Nws muaj ib tug standardized concentration. Piv txwv li, hydrochloric acid thiab sodium hydroxide yog cov kev daws teeb meem hauv cov chaw sim. Cov no tseem ceeb heev hauv kev npaj cov kev daws teeb meem uas xav tau rau titrations.
Txoj kev daws teeb meem yog dab tsi?
Ib txoj kev daws teeb meem yog ib qho kev daws teeb meem uas muaj kev paub meej meej. Hauv kev npaj cov txheej txheem kev daws teeb meem, peb tuaj yeem siv qhov hnyav hnyav hnyav thiab yaj nws hauv cov kuab tshuaj tsim nyog kom tau txais cov ntim tshwj xeeb ntawm cov tshuaj. Muaj ob hom kev daws teeb meem tseem ceeb thiab cov txheej txheem thib ob. Ib tus qauv tseem ceeb muaj qhov txaus siab meej, thiab peb tsis tas yuav ntsuas nws siv lwm cov tshuaj reagent. Cov txheej txheem thib ob yog cov txheej txheem reagent uas tau tsim los siv tus qauv thawj. Daim ntawv thov tseem ceeb ntawm cov qauv thawj thiab theem nrab yog los txiav txim siab qhov concentration ntawm cov reagent tsis paub, feem ntau hauv cov txheej txheem titration.
Cov no yog qee yam khoom tseem ceeb ntawm cov qauv kev daws teeb meem:
- Qhov kev xav tau tas li txhua lub sijhawm
- Reacts nrawm nrog tus kws tshuaj ntsuam
- Txoj kev rov ua kom tiav
- Tau piav qhia ntau npaum li cas siv cov tshuaj sib npaug sib npaug
- Tau pom qhov sib npaug, yog tias muaj.
Dab tsi yog qhov sib txawv ntawm Cov Khoom Muag Khoom thiab Cov Txheej Txheem Txheej Txheem?
Peb feem ntau siv cov lus cog lus thiab cov qauv kev daws teeb meem sib hloov. Qhov sib txawv tseem ceeb ntawm kev daws teeb meem thiab cov qauv kev daws teeb meem yog tias cov tshuaj hauv Tshuag yog cov tshuaj muaj zog heev, qhov kev daws teeb meem yog kev daws teeb meem uas muaj kev paub meej meej. Tsis tas li ntawd, cov tshuaj hauv Tshuag tuaj yeem yog qhov ntim loj ntawm cov ntsiab lus siab heev uas tuaj yeem yog cov tshuaj reagent, tab sis cov txheej txheem kev daws teeb meem muaj qee yam tshuaj lom neeg lossis cov khoom sib xyaw ntawm cov ntsiab lus meej heev.
Thaum xav txog lawv daim ntawv thov, cov kev daws teeb meem yog qhov tseem ceeb hauv kev txuag lub sij hawm npaj ntawm cov tshuaj reagents, txuag cov khoom, txo qhov chaw cia, thiab lwm yam thaum cov txheej txheem kev daws teeb meem yog qhov tseem ceeb hauv kev txiav txim siab qhov tsis paub txog qhov ntsuas ntawm qhov ntsuas.
Cov ntaub ntawv hauv qab no-daim duab qhia txog qhov sib txawv ntawm cov khoom lag luam thiab cov qauv kev daws teeb meem.
Summary – Stock Solution vs Standard Solution
Feem ntau ntawm lub sijhawm, peb tuaj yeem siv cov ntsiab lus kev daws teeb meem thiab cov txheej txheem kev hloov pauv. Qhov sib txawv tseem ceeb ntawm cov kev daws teeb meem thiab cov qauv kev daws teeb meem yog tias cov kev daws teeb meem yog cov tshuaj muaj zog heev, qhov kev daws teeb meem yog cov kev daws teeb meem uas muaj kev paub meej meej.
