Qhov concentration ntawm cov tshuaj yuav tseem nyob rau ntawm nws qhov siab tshaj plaws raws li koj muaj kev txhawj xeeb nrog cov nyiaj solute yaj.
Puas evaporation cuam tshuam qhov concentration?
Evaporation ua rau cov concentration ntawm ib qho tshuaj tsis txaus kom nce / txo / nyob twj ywm. Raws li cov tshuaj saturated (tsis muaj cov khib nyiab) yog diluted, nws cov concentration nce / qis / tseem zoo ib yam.
Yuav ua li cas thaum cov tshuaj evaporated?
Thaum cov tshuaj evaporates, dej nkag mus rau saum huab cua tab sis cov khoom tseem tshuav tom qab Tsim ib tus qauv los piav qhia qhov teeb meem yog ua los ntawm cov khoom me me dhau los pom. dissolving thiab evaporation tshwm sim ntawm qib particle; thiab cov qauv ntawd tuaj yeem pab piav qhia cov txheej txheem no uas peb tsis tuaj yeem pom.
Cov txiaj ntsig dab tsi ua rau cua sov cov tshuaj kom evaporate qee cov kuab tshuaj muaj nyob rau hauv cov concentration ntawm cov tshuaj?
Yog tias koj yuav ua kom sov cov tshuaj, ua rau cov kuab tshuaj evaporate, koj yuav tau tsom nws, vim qhov piv ntawm cov kuab tshuaj rau cov kuab tshuaj yuav nce ntxiv Yog tias koj ntxiv Cov dej ntau dua rau cov tshuaj aqueous, koj yuav tau diluting nws vim qhov piv ntawm cov kuab tshuaj rau cov kuab tshuaj yuav txo qis.
Koj ua li cas txo qhov concentration ntawm cov tshuaj?
Qhov concentration tuaj yeem txo tau los ntawm 2 txoj hauv kev, los ntawm kev nce cov kua dej, lossis txo cov dej. Ua kom cov kuab tshuaj ntxiv yuav ua rau kom cov tshuaj concentration. Qhov no tuaj yeem ua tiav los ntawm qhov yooj yim ntxiv koj cov khoom sib xyaw rau hauv cov tshuaj thiab ua kom yaj nws.
