Rau cais qhov no sib tov ntawm pigments uas yog ob dyes, ntawv chromatography yog siv. Ib feem me me ntawm cov sib tov muab tso rau hauv cov khoom siv absorbent, ib daim ntawv lim, nrog rau cov kuab tshuaj. Ob lub dyes yuav txav sib cais thiab cov tus cwj mem yuav cais rau hauv nws cov khoom ntshiab.
Hais txog qhov no, koj ua li cas cais tus cwj mem?
Ua tus cwj mem chromatography, koj muab ib qho me me ntawm tus cwj mem yuav tsum tau muab cais rau ntawm ib kawg ntawm ib tug strip ntawm lim ntawv. Qhov kawg ntawm daim ntawv strip yog muab tso rau hauv ib qho hnyav. Cov kuab tshuaj txav mus rau ntawm daim ntawv sawb thiab, thaum nws nce mus, nws dissolves cov tshuaj sib tov thiab rub lawv mus rau hauv daim ntawv.
Tsis tas li ntawd, koj yuav cais cov khoom ntawm tus cwj mem siv chromatography li cas? Thaum koj tso chromatography daim ntawv rau hauv ib qho hnyav, qhov hnyav pib txav mus rau daim ntawv. Raws li qhov hnyav nce, nws dissolves lub tus cwj mem ntawm daim ntawv thiab cais cov tus cwj mem hauv nws cov khoom . Qhov deb ntawm tus cwj mem mus ncig, qhov ntau nws yog attracted rau cov kuab tshuaj.
Tsis tas li ntawd, koj yuav ua li cas cais cov xim hauv cov xim dub?
Nyob rau hauv lub khob kas fes lim, dej hauv lub tus cwj mem nqa lub xim rau ntawm daim ntawv. Thaum lub tus cwj mem dries, cov xim tseem nyob ntawm daim ntawv. Thaum koj dipped daim ntawv nyob rau hauv dej, lub qhuav pigments yaj. Raws li cov dej nkag mus rau hauv daim ntawv, nws nqa lub pigments nrog nws.
Yuav ua li cas cais tus number case los ntawm dej?
Cais tus number case los ntawm dej siv cov txheej txheem hu ua distillation. Qhov no yog txheej txheem ntawm kev sib cais ob yam khoom sib xyaw ua ke. Dej vaporizes ntawm qhov kub thiab txias tshaj qhov tus cwj mem pigment yog li yog tias koj sov lawv, lub dej evaporates, tawm hauv tus cwj mem pigment nyob rau hauv lub khob.

Koj yuav ua li cas cais ib qho khoom thiab sib tov?
Cov ntsiab lus sib xyaw tuaj yeem sib cais siv ntau hom kev kawm. Chromatography suav nrog kev sib cais hnyav ntawm cov khoom nruab nrab. Distillation siv qhov zoo ntawm qhov sib txawv ntawm cov ntsiab lus kub. Evaporation tshem tawm cov kua los ntawm kev daws kom tawm hauv cov khoom siv. Lim cais cov khib nyiab ntawm qhov sib txawv
Yuav ua li cas tshwm sim thaum koj sib tov ib tug muaj zog acid nrog ib tug tsis muaj zog puag?
Hom 2: thaum muaj zog acid / base reacts nrog lub hauv paus tsis muaj zog / acid yog hydronium thiab hydroxyl ions tam sim no nyob rau hauv sib npaug amt ces ntsev thiab dej yog tsim thiab lub zog tso tawm uas tsawg tshaj li 57 kj / mole vim lub dissociation ntawm lub tsis muaj zog acid / puag uas feem ntau endothermic
Yuav ua li cas koj cais ib tug sib tov ntawm xuab zeb thiab ntsev?
Sib cais ntsev thiab xuab zeb Siv Solubility Ncuav ntsev thiab xuab zeb sib tov rau hauv lub lauj kaub. Ntxiv dej. Kub dej kom txog thaum ntsev yaj. Tshem lub lauj kaub los ntawm tshav kub thiab cia nws txias kom txog thaum nws muaj kev nyab xeeb. Ncuav dej ntsev rau hauv ib lub thawv cais. Tam sim no sau cov xuab zeb
Koj yuav daws qhov sib npaug li cas los ntawm kev cais qhov sib txawv?
Cov txheej txheem yooj yim los cais qhov sib txawv yog "ua ib yam dab tsi rau ob tog" ntawm qhov sib npaug, xws li ntxiv, rho tawm, sib npaug, lossis faib ob sab ntawm qhov sib npaug los ntawm tib tus lej. Los ntawm kev rov ua cov txheej txheem no, peb tuaj yeem tau txais qhov sib txawv ntawm ib sab ntawm qhov sib npaug
Yuav siv txoj kev twg los cais cov khoom ntawm tus number case?
Chromatography yog ib txoj hauv kev los tshuaj xyuas cov khoom sib tov los ntawm kev sib cais rau hauv cov tshuaj uas lawv tau tsim. Nws tuaj yeem siv los cais cov khoom sib xyaw xws li tus cwj mem, ntshav, roj av, thiab daim di ncauj. Hauv ink chromatography, koj tab tom sib cais cov xim xim uas ua rau cov xim ntawm tus cwj mem
