Qhov Tseem Ceeb Qhov Sib Txawv - Dilution vs Dilution Factor
Dilution thiab dilution factor yog cov ntsiab lus siv rau kev suav hauv chemistry analytical. Dilution yog hais txog qhov txo qis ntawm cov concentration ntawm ib qho kev daws teeb meem hauv kev daws teeb meem. Lo lus no tuaj yeem siv los piav txog cov kua thiab roj. Dilution yam yog ib qho kev ntsuas ntawm dilution; nws piav qhia txog qhov dilution. Qhov sib txawv tseem ceeb ntawm dilution thiab dilution yam yog qhov dilution ntawm ib qho kev daws yog qhov txo qis ntawm cov concentration ntawm cov kua hauv cov tshuaj ntawd whereas dilution factor yog qhov sib piv ntawm qhov kawg ntim thiab thawj ntim ntawm cov tshuaj.
Dilution yog dab tsi?
Dilution of a solution yog qhov txo qis ntawm cov concentration ntawm cov kuab tshuaj hauv cov tshuaj ntawd. Kev daws yog tsim los ntawm cov kuab tshuaj uas tau yaj cov kuab tshuaj hauv nws. Qhov concentration ntawm cov tshuaj no yog muab raws li molarity los yog molality. Molarity yog tus nqi ntawm cov kuab tshuaj uas muaj nyob rau hauv ib chav ntim ntawm kev daws (muab los ntawm chav tsev mol / L). Mollality yog qhov loj ntawm cov kua dej tam sim no hauv ib chav tsev ntim (muab los ntawm kg / L). Thaum lub concentration ntawm cov kua nyob rau hauv cov tshuaj no txo, nws yog hu ua ib tug diluted tov.
Ib lub dilution yog ua los ntawm tsuas yog ntxiv cov kuab tshuaj ntau ntxiv rau cov tshuaj, tuav cov ntsiab lus solute ib ntus. Piv txwv li, cov tshuaj aqueous uas muaj sodium chloride (NaCl) tuaj yeem diluted los ntawm kev ntxiv dej ntxiv. Yog tias cov kua nplaum yog cov xim sib xyaw, cov xim ntawm cov tshuaj yuav ploj mus thaum cov tshuaj tau diluted.

Qhov kawg ntawm cov tshuaj tuaj yeem txiav txim siab siv cov kev sib raug zoo hauv qab no.
C1V1=C2V2
C1 yog thawj qhov concentration
V1 yog qhov pib ntim
C2 yog qhov kawg concentration
V2 yog qhov kawg ntim ntawm kev daws.
Ex: Cov tshuaj aqueous ntawm KCl muaj 2.0 moles ntawm KCl hauv 0.2 L dej. Dab tsi yuav yog qhov kawg ntawm cov tshuaj KCl yog dej (400 mL) ntxiv?
Initial concentration of KCl (C1)=2.0 mol/0.2L=10 mol/L
Qhov ntim ntawm cov tshuaj (V1)=0.2 L
Qhov kawg ntim ntawm cov tshuaj (V2)=0.2 L + 0.4 L=0.6 L
Qhov kawg ntawm kev daws (C2) tuaj yeem txiav txim siab siv:
C1V1=C2V2
10 mol/L x 0.2 L=C2 x 0.6 L
C2=2 mol / 0.6 L=3.33 mol / L
Dilution Factor yog dab tsi?
Dilution factor (tseem hu ua dilution ratio) yog qhov piv ntawm qhov kawg ntim thiab thawj ntim ntawm cov tshuaj. Qhov kawg ntim yog qhov ntim ntawm cov tshuaj tom qab dilution. Thawj ntim yog qhov ntim ntawm cov tshuaj ua ntej dilutes, los yog lub ntim ntawm thawj cov tshuaj siv rau dilution. Qhov kev sib raug zoo no kuj tseem siv tau nrog rau qhov loj ntawm qhov solute.
Dilution Factor Calculation
Dilution factor=qhov kawg ntim (V2) / thawj ntim (V1)
Ex: Dilution ntawm 200 mL ntawm KMnO 4 aqueous tov los ntawm kev ntxiv 200mL dej,
Dilution factor=(200mL + 200mL) / 200mL
=400 mL / 200mL
=2

Summary – Dilution vs Dilution Factor
Dilution thiab dilution factor yog cov ntsiab lus ntau hauv chemistry. Dilution factor yog qhov ntsuas ntawm dilution. Qhov sib txawv tseem ceeb ntawm dilution thiab dilution yam yog qhov dilution ntawm ib qho kev daws yog qhov txo qis ntawm cov concentration ntawm cov kua hauv cov tshuaj ntawd whereas dilution factor yog qhov piv ntawm qhov kawg ntim thiab thawj ntim ntawm cov tshuaj.
