Qhov loj dua solubility ntawm ib tug solute, qhov ntau dua qhov kub point . Yog hais tias peb muaj ob lub tebchaw sib piv, qhov ntau soluble compound yuav muaj ntau hais nyob rau hauv kev daws. Nws yuav muaj molarity ntau dua. Cov kub point elevation, thiab li no kub point , yuav siab dua rau ntau soluble compound.
Yog li ntawd, puas boiling point cuam tshuam solubility?
Cov kub point thiab melting point ua tsis yog cuam tshuam tus solubility ntawm ib tug compound (tshwj tsis yog tias koj txhob txwm mus sim yaj lawv ntawm cov kub uas tiv thaiv kev daws teeb meem). Kev sib zog ua kom muaj zog ntau dua ua rau siab dua cov ntsiab lus kub thiab melting cov ntsiab lus . Solubility txawm li cas los xij, yog qhov nyuaj me ntsis.
Ib yam li ntawd, puas solubility nce lossis txo nrog qhov kub thiab txias? Nce kub ua an nce hauv kinetic zog. Lub zog kinetic siab dua ua rau muaj kev txav ntau dua hauv cov roj molecules uas rhuav tshem cov ntawv cog lus intermolecular thiab khiav tawm ntawm kev daws. Raws li cov kub nce , cov solubility ib gas txo raws li qhia los ntawm qhov kev poob qis hauv daim duab.
Tsis tas li cov lus nug yog, vim li cas cov ntsiab lus boiling nce thaum cov kua dej ntxiv?
Txawm tsis muaj nqi daws , ntxiv particles rau dej nce lub kub point vim hais tias ib feem ntawm lub siab cov tshuaj exerts ntawm cov huab cua tam sim no los ntawm daws hais, tsis yog cov kuab tshuaj (dej) molecules xwb. Cov dej molecules xav tau lub zog ntau dua los tsim kom muaj siab txaus kom khiav tawm ntawm cov dej ciam teb.
Puas siab molarity txhais tau tias siab dua qhov kub?
1 Teb. Thaum twg cov khoom uas tsis yog-volatile yog yaj nyob rau hauv ib tug hnyav, lub kub point ntawm qhov hnyav nce. Cov siab dua cov concentration (molality), cov siab dua tus kub point . Koj tuaj yeem xav txog cov txiaj ntsig no li cov kuab tshuaj lom neeg tawm ntawm cov kuab tshuaj molecules ntawm qhov chaw, qhov twg boiling tshwm sim.

Yuav ua li cas koj xam qhov boiling point elevation?
Qhov sib npaug yooj yim rau kev txiav txim siab kub ntawm qhov kev daws teeb meem: delta T = mKb. Delta T yog hais txog qhov kub ntawm qhov nce siab, lossis ntau npaum li cas qhov kev daws qhov boiling point yog ntau dua li cov kuab tshuaj ntshiab. Cov units yog degrees Celsius. Kb yog molal boiling point elevation tas li
