Supersaturation tshwm sim nrog cov tshuaj tov thaum cov concentration ntawm cov kua dej ntau tshaj qhov concentration teev los ntawm tus nqi sib npaug ntawm solubility. … Ib qho tshuaj supersaturated nyob rau hauv lub xeev metastable; Nws tuaj yeem raug coj mus rau qhov sib npaug los ntawm kev yuam kom dhau ntawm cov kuab tshuaj kom cais tawm ntawm cov tshuaj.
Yuav ua li cas super saturation tshwm sim?
Gas supersaturation tshwm sim thaum tag nrho cov roj yaj hauv lub cev dej tshaj qhov concentration ntawm tag nrho cov pa roj uas tuaj yeem yaj tau raws li qhov xwm txheej tau muab qhov kub, yaj, thiab roj. siab saum dej (feem ntau yog txiav txim siab los ntawm qhov siab).
Koj piav qhia txog supersaturation li cas?
A cov tshuaj supersaturated yog cov tshuaj uas muaj ntau tshaj li qhov siab tshaj ntawm cov kua uas muaj peev xwm ua kom yaj ntawm qhov kub thiab txias. Lub recrystallization ntawm cov kua dej ntau dhau hauv cov tshuaj supersaturated tuaj yeem pib los ntawm qhov sib ntxiv ntawm me me crystal of solute, hu ua noob siv lead ua.
Yuav ua li cas cov tshuaj supersaturated tsim?
Ib qho tshuaj aqueous tuaj yeem ua tau supersaturated los ntawm ua ntej dissolving cov kua nyob rau hauv dej ntawm qhov kub siab uas siv txaus los muab ib tug concentration nyob rau hauv nws solubility ntawm qhov kub thiab txias. Tom qab qhov kawg ntawm cov kua nplaum uas tau yaj lawm cov tshuaj yog txias.
Vim li cas cov kev daws thiaj li nkag siab?
(a) Thaum muaj zogyog ntxiv rau cov kuab tshuaj nyob rau hauv uas nws yog soluble, solute hais tawm ntawm qhov chaw ntawm cov khoom thiab ua solvated los ntawm cov hnyav, pib tsim ib unsaturated tov. (b) Thaum qhov ntau tshaj qhov ua tau ntawm cov kuab tshuaj tau yaj, cov tshuaj yuav saturated.
