Mov kom huv si kom yaj lub solute Thaum cov kuab tau yaj lawm, ntxiv cov kuab tshuaj uas tseem tshuav los ua cov tshuaj uas xav tau ntim thiab sib tov kom huv si. Piv txwv li, ua 0.5 Litres ntawm 0.5 molar NaCl: … Ua ib qho kev daws teeb meem ntawm ib qho concentration ntawm cov tshuaj hauv Tshuag yog hu ua dilution.
Koj puas ntxiv cov kuab tshuaj rau qhov solute?
Thaum lub solute tau yaj lawm, ntxiv cov kuab tshuaj ntxivkom cov tshuaj ntawm qhov xav tau ntim thiab sib tov kom huv si. … Thaum diluting ib qho kev daws, nco ntsoov tias ntxiv cov kuab tshuaj rau cov tshuaj hloov cov concentration ntawm cov tshuaj, tab sis tsis yog tus nqi ntawm cov kua uas twb muaj lawm.
Koj puas ntxiv cov kuab tshuaj lossis cov kuab tshuaj ua ntej?
Ntxiv cov kuab tshuaj rau hauv lub khob ua ntej ua ntej ntxiv cov kuab tshuaj. Qhov no yuav zam tsis ntxiv cov kuab tshuaj ntau dhau rau cov tshuaj. Koj yuav tsum cia qhuav solute kom yaj hauv cov kuab tshuaj ua ntej ua ntej ntxiv rau tag nrho ntim.
Vim li cas koj ntxiv cov kuab tshuaj rau cov kuab tshuaj?
Thaum ib cov kuab tshuaj ntxiv rau cov kuab tshuaj, qee cov kua molecules nyob hauv qhov chaw ze ntawm cov kua, raws li qhia hauv daim duab hauv qab no. Thaum cov kuab tshuaj yaj nyob rau hauv cov kuab tshuaj, cov kuab tshuaj molecules nyob ze ntawm qhov chaw txo, thiab lub vapor siab ntawm cov kuab tshuaj txo.
Yuav ua li cas yog tias koj ntxiv cov kuab tshuaj ntxiv rau cov kuab tshuaj?
Qhov concentration ntawm cov tshuaj tuaj yeem txo qis ntxiv, lossis diluted, los ntawm kev ntxiv cov kuab tshuaj ntxiv. Ntawm qhov tod tes, raws li ntau cov kuab tshuaj ntxiv rau hauv cov tshuaj, cov tshuaj ua kom muaj zog ntau dua…

Puas yog kas fes yog kuab los yog kuab tshuaj?
Thaum koj brew kas fes, koj tab tom tsim kev daws teeb meem. Cov me me ntawm cov hauv paus kas fes, los yog cov kuab tshuaj, yog dissolved hauv dej, cov kuab tshuaj . Puas yog khob kas fes yog kuab los yog kuab tshuaj? Cov qab zib uas koj ntxiv rau hauv khob kas fes yog lub npe hu ua tus soluteThaum cov kua dej no ntxiv rau cov kua, uas yog hu ua cov kuab tshuaj, cov txheej txheem dissolving pib.
Koj puas tuaj yeem ntxiv tshuaj dawb rau koj lub tshuab ntxuav tais diav?
Phos 1 khob tshuaj dawb rau hauv lub tshuab ntxuav tais diav-zoo, tshuaj ntxuav tais diav thiab muab tso rau saum khib ntawm koj lub tshuab ntxuav tais diav. Tom qab ntawd khiav tag nrho lub voj voog, tab sis hla lub voj voog kom qhuav. Tswv yim:
Thaum cov kuab tshuaj evaporates dab tsi tshwm sim rau qhov concentration ntawm cov tshuaj?
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 dej ntws mus rau cov kuab tshuaj?
Cov ntsev thiab suab thaj hauv cov tshuaj yuav tawm mus deb ntawm thaj chaw uas muaj siab rau hauv cov tshuaj ib puag ncig. Qhov no yog hu ua yooj yim diffusion. Dej kuj diffuses deb ntawm thaj chaw ntawm cov dej dawb siab concentration mus rau thaj tsam ntawm ntau cov kua qaub .
Yuav ua rau kom cov solubility ntawm cov kuab tshuaj feem ntau?
Rau ntau cov khib nyiab yaj hauv cov dej ua kua, solubility nce nrog qhov kub thiab txiasKev nce hauv lub zog kinetic uas los nrog qhov kub siab dua tso cai rau cov kuab tshuaj molecules kom zoo dua sib cais cov kuab tshuaj molecules uas tau tuav ua ke los ntawm kev sib txuas lus sib txuas .
