Qhov Tseem Ceeb Qhov txawv - Saturated vs Concentrated Solution
Ib tshuaj yog ib theem ua kua ntawm cov teeb meem uas yog tsim los ntawm dissolving ib tug solute nyob rau hauv ib tug hnyav. Ib qho tshuaj tuaj yeem hloov mus rau hauv cov tshuaj saturated los ntawm kev ntxiv cov kuab tshuaj kom txog thaum tsis muaj cov kuab tshuaj ntxiv lawm. Ib qho kev daws teeb meem muaj ntau qhov ntau ntawm cov kuab tshuaj, tab sis tus nqi ntawd tsis yog qhov siab tshaj plaws. Qhov sib txawv tseem ceeb ntawm saturated thiab concentrated tov yog tias ntxiv cov kuab tshuaj tsis tuaj yeem yaj hauv cov tshuaj saturated vim tias nws muaj cov kuab tshuaj ntau tshaj plaws thaum ntxiv cov kuab tshuaj tuaj yeem yaj hauv cov tshuaj concentrated vim tias nws tsis muaj qhov ntau tshaj ntawm cov kuab tshuaj (tsis saturated. nrog tus solute).
Saturated Solution yog dab tsi?
A saturated tov yog cov tshuaj tov uas muaj qhov siab tshaj plaws ntawm cov kuab tshuaj yaj hauv cov kuab tshuaj. Cov tshuaj ntxiv tsis tuaj yeem yaj hauv cov tshuaj saturated vim tias nws muaj cov kuab tshuaj ntau tshaj plaws. Daim ntawv rov qab ntawm cov tshuaj saturated yog cov tshuaj unsaturated. Cov tshuaj unsaturated tsis saturated nrog cov kua. Ib qho tshuaj tsis txaus ntseeg tuaj yeem yog cov tshuaj muaj zog lossis cov tshuaj dilute.
Muaj ntau yam uas cuam tshuam rau kev ua kom lub cev qhuav dej. Cov xwm txheej no cuam tshuam rau kev tawg ntawm cov kuab tshuaj hauv cov kuab tshuaj.
- Kub - Lub solubility ntawm cov khoom sib txuas nce nrog nce qhov kub ntawm cov kuab tshuaj. Yog li ntawd, ntau cov kuab tshuaj tuaj yeem yaj hauv cov kuab tshuaj kub ntau dua li cov kuab tshuaj txias.
- Pressure - Ntau cov kuab tshuaj tuaj yeem ua rau lub zog kom tau yaj hauv cov kuab tshuaj los ntawm kev siv lub siab. Yog li ntawd, kev sib cais ntawm cov kuab tshuaj tuaj yeem nce ntxiv los ntawm kev ua kom lub zog ntawm qhov system. Ex: Gases.
- Tshuaj muaj pes tsawg leeg - Yog tias qee qhov lwm cov kuab tshuaj twb muaj nyob rau hauv cov tshuaj, nws cuam tshuam rau solubility ntawm solutes.
Ib qho tshuaj saturated tuaj yeem tsim los ntawm kev ntxiv cov kuab tshuaj rau cov kuab tshuaj kom txog thaum tsis muaj cov kuab tshuaj ntxiv lawm. Los yog lwm yam, nws tuaj yeem ua tau los ntawm evaporating cov kuab tshuaj ntawm cov kuab tshuaj kom txog thaum cov kua qaub pib tsim cov muaju. Lwm txoj kev, tab sis tsis yog ntau ntau yog ntxiv cov noob ntawm cov muaju rau cov tshuaj supersaturated. Ib qho tshuaj supersaturated muaj ntau cov kuab tshuaj uas nyob twj ywm yaj txawm tias cov tshuaj txias. Thaum cov noob ntawm cov muaju ntxiv rau cov tshuaj supersaturated no, cov kuab tshuaj pib crystallize, muab cov tshuaj saturated.
Daim duab 01: Cov kua txiv hmab txiv ntoo yog cov tshuaj saturated
Qee yam piv txwv ntawm cov tshuaj saturated muaj xws li cov dej carbonated (saturated nrog carbon), saturated qab zib tov (tsis muaj suab thaj ntau yuav yaj), npias los yog sparkling kua txiv yog saturated nrog carbon dioxide, thiab lwm yam.
Kev daws teeb meem yog dab tsi?
A cov tshuaj concentrated yog cov tshuaj tshuaj uas muaj cov kuab tshuaj ntau hauv cov kuab tshuaj. Cov kua nplaum ntxiv tuaj yeem yaj hauv cov tshuaj concentrated vim tias nws tsis muaj qhov ntau ntawm cov kua nplaum (tsis saturated nrog cov kua nplaum). Daim ntawv rov qab ntawm cov tshuaj concentrated yog dilute tov. Cov tshuaj dilute muaj ib qho qis ntawm cov kuab tshuaj yaj hauv cov kuab tshuaj.
Daim duab 02: Cov tshuaj muaj zog (txoj cai) muaj xim muaj zog piv rau cov tshuaj diluted (sab laug)
Cov ntsiab lus ntawm cov kua qaub lossis cov hauv paus tau lees paub tias yog cov kua qaub muaj zog lossis cov hauv paus muaj zog. Nyob rau hauv sib piv, dilute acids los yog bases yog qaug zog acids los yog bases. Lo lus concentrated yog siv los muab lub tswv yim ntau txog kev daws teeb meem. Ib qho kev daws teeb meem tuaj yeem tsim los ntawm kev yaj ntau cov kua rau hauv ib qho kev daws los yog los ntawm evaporating ib qho kev daws kom txog thaum muaj ntau npaum li cas ntawm cov kuab tshuaj evaporated tawm hauv cov kuab tshuaj. Qhov concentration ntawm cov tshuaj tuaj yeem muab tau raws li hauv qab no. Muaj qhov concentration yog muab los ntawm chav tsev mol / L.
Concentration=tus naj npawb ntawm moles ntawm solutes / ntim ntawm cov tshuaj
Dab tsi yog qhov zoo sib xws ntawm Saturated thiab Concentrated Solution?
- Ob qho tib si Saturated thiab Concentrated Solution yog cov kev daws teeb meem uas muaj ntau cov ntsiab lus
- Ob lub ntsiab lus Saturated thiab Concentrated Solution qhia ntau lub tswv yim txog kev daws teeb meem.
Qhov txawv ntawm Saturated thiab Concentrated Solution yog dab tsi?

Summary – Saturated vs Concentrated Solution
A saturated tov yog ib daim ntawv ntawm cov tshuaj concentrated, tab sis nws muaj qhov siab tshaj plaws ntawm cov kuab tshuaj uas tuaj yeem tuav tau. Qhov sib txawv ntawm saturated thiab concentrated tov yog hais tias ntxiv solutes tsis tau yaj nyob rau hauv ib tug saturated tov vim nws muaj ntau npaum li cas ntawm solutes whereas ntxiv solutes yuav yaj nyob rau hauv ib tug concentrated tov vim hais tias nws tsis muaj ntau npaum li cas ntawm solutes (tsis saturated nrog. cov solute).
