Qhov sib txawv tseem ceeb ntawm dilution thiab concentration yog tias dilution hais txog qhov sib ntxiv ntawm cov kuab tshuaj ntau dua whereas concentration yog hais txog kev tshem tawm cov kuab tshuaj.
Lub ntsiab lus ntawm kev dilution thiab concentration yog qhov tseem ceeb hauv kev kawm txog kev daws teeb meem hauv chemistry. Yog li ntawd, tus nqi ntawm cov kuab tshuaj nyob rau hauv ib tug hnyav txiav txim lub zog ntawm ib tug tov thiab cov nyiaj no tseem tshuav tib yam; peb tuaj yeem ua cov tshuaj "diluted" lossis "concentrated" los ntawm kev ntxiv cov kuab tshuaj thiab tshem tawm qee qhov hnyav ntawm cov tshuaj. Yog li, hauv kev tshuaj xyuas tshuaj, peb yuav tsum tau hloov qhov concentration ntawm cov tshuaj feem ntau hauv cov ntawv thov sib txawv.
Dilution yog dab tsi?
Dilution yog tus txheej txheem ntawm kev txo cov concentration ntawm cov kuab tshuaj hauv cov tshuaj los ntawm kev ntxiv cov kuab tshuaj ntxiv. Yog li ntawd, peb tuaj yeem txo tus nqi ntawm cov kuab tshuaj tam sim no hauv ib chav ntim ntawm cov tshuaj. Yog tias peb xa mus rau "kom dilute", nws txhais tau tias, "kom ntxiv cov kuab tshuaj ntxiv yam tsis ntxiv cov kuab tshuaj". Txawm li cas los xij, tom qab qhov sib ntxiv ntawm cov kuab tshuaj, peb yuav tsum sib tov cov tshuaj kom zoo thiaj li tau txais cov tshuaj homogeneous.
Daim duab 01: Txheej txheem ntawm Dilution
Raws li qhov sib npaug hauv qab no, peb tuaj yeem txiav txim siab qhov kawg ntawm cov tshuaj tom qab cov txheej txheem dilution.
C1V1=C2V2
Qhov twg, C1 yog thawj zaug concentration, V1 yog thawj ntim ntawm cov tshuaj, C2 yog qhov concentration tom qab dilution thiab V2 yog qhov kawg concentration ntawm cov tshuaj. Piv txwv li, yog tias peb ntxiv 5 mL dej rau 95 mL ntawm cov dej aqueous ntawm NaCl (1 mol / L), ces qhov dilution muab 0.95 mol / L tov. Li no qhov concentration yog txo.
Kev Cuam Tshuam yog dab tsi?
Concentration yog txheej txheem ntawm kev ua kom cov concentration ntawm cov kuab tshuaj nyob rau hauv ib qho kev daws. Hauv lwm lo lus, nws yog qhov txo qis ntawm cov kuab tshuaj los yog nce tus nqi ntawm cov kuab tshuaj. Yog li ntawd, nws yog tus txheej txheem ntawm nce tus nqi ntawm solutes tam sim no nyob rau hauv ib chav tsev ntim ntawm cov tshuaj.
Daim duab 02: Txheej txheem ntawm Kev Cuam Tshuam darkens the Solution`
A cov tshuaj concentrated muaj ntau cov kuab tshuaj piv rau cov tshuaj diluted. Peb tuaj yeem txiav txim siab qhov concentration ntawm qhov kev daws teeb meem tom qab nws siv tib qhov sib npaug uas tau muab los saum toj no (nyob rau hauv subtopic dilution).
Qhov txawv ntawm Dilution thiab Concentration yog dab tsi?
Dilution yog cov txheej txheem ntawm kev txo cov concentration ntawm cov kuab tshuaj hauv cov tshuaj los ntawm kev ntxiv cov kuab tshuaj ntau dua whereas concentration yog cov txheej txheem ntawm kev nce cov concentration ntawm cov kuab tshuaj hauv cov tshuaj. Yog li, qhov sib txawv tseem ceeb ntawm dilution thiab concentration yog tias dilution hais txog qhov sib ntxiv ntawm cov kuab tshuaj ntau dua whereas concentration hais txog kev tshem tawm cov kuab tshuaj. Peb tuaj yeem dilute ib qho kev daws los ntawm kev ntxiv cov kuab tshuaj ntau dua lossis los ntawm kev tshem tawm cov kuab tshuaj thaum cov txheej txheem ntawm cov concentration muaj xws li ntxiv cov kuab tshuaj ntxiv lossis tshem tawm cov kuab tshuaj.
Cov hauv qab no infographic muab cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov concentration.
Summary – Dilution vs Concentration
Dilution thiab concentration yog ib qho tseem ceeb heev hauv chemistry los npaj cov kev daws teeb meem nrog qhov xav tau concentration. Tsis tas li ntawd, cov txheej txheem ntawm dilution thiab concentration yog ib qho tseem ceeb heev nyob rau hauv analytical chemistry. Qhov sib txawv tseem ceeb ntawm dilution thiab concentration yog tias dilution hais txog qhov sib ntxiv ntawm cov kuab tshuaj ntau dua whereas concentration hais txog kev tshem tawm cov kuab tshuaj.
