CEEB TOOM: Hauv ob qho tib si sib cais funnels, liab txheej yog cov aqueous txheej . Nyob rau sab laug sib cais funnel, lub aqueous txheej yog nyob rau hauv qab, txhais tau tias cov organic txheej yuav tsum tsawg dua dej. Nyob rau hauv txoj cai sib cais funnel, lub aqueous txheej yog nyob rau sab saum toj, txhais tau tias cov organic txheej yuav tsum yog tuab dua dej.

Tsis tas li ntawd, koj yuav txiav txim siab li cas txheej twg yog aqueous thiab txheej twg yog cov organic thaum lub sij hawm rho tawm?

Rau txiav txim seb txheej twg yog qhov twg, ib tus tuaj yeem ntxiv cov dej distilled rau lub funnel. Qhov twg txheej nce hauv qhov loj me yuav tsum yog aqueous txheej thiab lwm yam yog tus organic txheej . Hauv qhov no, ob qho tib si txheej tuaj yeem muab cais rau hauv lawv cov beakers.

Qhov thib ob, lub sijhawm aqueous yog dab tsi? dej theem (plural aqueous theem ) Homogeneous ib feem ntawm lub heterogeneous system uas muaj dej los yog ib tug tov nyob rau hauv dej ntawm ib yam khoom.

Xav txog qhov no, koj tuaj yeem ua li cas yog tias koj tsis paub tias txheej twg yog qhov twg hauv cov txheej txheem rho tawm?

Tso dej me me rau hauv lub caj dab ntawm qhov sib cais funnel. Saib nws ua tib zoo: yog nws tseem nyob rau sab sauv txheej , uas txheej yog cov dej txheej.

Dab tsi yog theem ntawm cov organic hauv kev rho tawm?

Qhov loj dua tus nqi ntawm K, tus solute yuav pom nyob rau hauv ntau dua nyob rau hauv lub organic kuab tshuaj. Hauv ib rho tawm txheej txheem, aqueous theem , feem ntau yog dej, thiab immiscible organic kuab tshuaj hu ua organic theem feem ntau shaken nyob rau hauv ib lub thawv.
