Qhov no txhais tau hais tias yog tias koj cov kuab tshuaj evaporating thiab qhov kub thiab txias tsis tu ncua, ces solute yuav precipitate tawm ntawm cov tshuaj. 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?

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.
