12.6 Vapor Pressures of Solutions- Vapor siab txo qis, qhov chaw khov kev nyuaj siab, kub point elevation, thiab osmotic siab yog colligative properties-properties uas nyob ntawm seb cov kuab tshuaj tshwj xeeb thiab nyob ntawm tus naj npawb ntawm cov ntsiab lus solute tam sim no, tab sis tsis nyob ntawm tus kheej ntawm cov kuab tshuaj.

Hauv qhov no, Kev daws puas yog lub cev khoom ntiag tug?

13: Cov khoom ntawm Kev daws teeb meem . Nyob rau hauv tag nrho kev daws teeb meem Txawm hais tias gaseous, kua, los yog khoom, cov khoom muaj nyob rau hauv qhov loj tshaj plaws yog cov kuab tshuaj, thiab cov khoom los yog cov khoom uas muaj nyob rau hauv tsawg dua yog cov kuab tshuaj. Kev tsim ntawm a daws los ntawm cov kuab tshuaj thiab cov kuab tshuaj yog ib lub cev process, tsis a tshuaj ib.

Tom qab, lo lus nug yog, puas yog molarity yog lub cev khoom? 2 Teb. Concentration yog intensive vaj tse . Tus nqi ntawm cov vaj tse tsis hloov nrog scale. Concentration (xws li molarity ) - ratio ntawm tus nqi ntawm solute (ntau, ntim, los yog moles) rau tus nqi ntawm cov tshuaj (mas los yog ntim feem ntau)

Tsis tas li ntawd, cov txiaj ntsig ntawm cov lus teb yog dab tsi?

Teb. Cov khoom sib koom ua ke yog cov yam ntxwv uas muaj kev daws teeb meem nyob ntawm tus lej, tsis yog tus kheej, ntawm cov khoom sib tov. Hauv kev daws teeb meem, cov vapor siab yog qis, cov kub point yog siab dua, qhov chaw khov yog qis dua, thiab osmotic siab yog siab dua.

Dab tsi yog 3 yam khoom ntawm kev daws teeb meem?

Cov khoom sib koom ua ke yog cov yam ntxwv muaj kev daws teeb meem uas nyob ntawm seb muaj pes tsawg tus solute hais, tsis yog tus kheej. Rau cov kua, muaj qhov qis dua vapor siab, siab dua kub point , txo qhov chaw khov, thiab siab dua osmotic.
