Yuav ua li cas anhydrous sodium sulfate tshem tawm dej

Anhydrous sodium sulfate yog dav siv los ua lub cev qhuav dej hauv ntau yam tshuaj thiab kev lag luam. Nws muaj lub peev xwm tshwj xeeb los tshem tawm cov dej los ntawm cov kua thiab cov tshuaj gaseous los ntawm adsorbing dej molecules ntawm nws qhov chaw. Hauv tsab xov xwm no, peb yuav tshawb xyuas yuav ua li cas anhydrous sodium sulfate tshem tawm dej los ntawm ntau qhov chaw thiab yuav ua li cas ua tiav qhov no.

Tab sis ua ntej ntawm tag nrho cov, dab tsi yog anhydrous sodium sulfate? Nws yog ib qho dawb tsis muaj ntxhiab crystalline compound nrog cov tshuaj formula Na2SO4. Tsis zoo li daim ntawv hydrated (Na2SO4.10H2O), anhydrous sodium sulfate tsis muaj dej molecules, thiab daim ntawv hydrated muaj 10 dej molecules ib chav tsev formula. Tam sim no cia peb tham txog lub hauv paus ntsiab lus ntawm lub cev qhuav dej nrog anhydrous sodium sulfate. Lub tswv yim tseem ceeb yog tias anhydrous sodium sulfate muaj kev sib raug zoo rau cov dej molecules thiab tuaj yeem ua ke nrog cov dej molecules los ntawm hydrogen bonding. Qhov no txhais tau hais tias thaum anhydrous sodium sulfate los rau hauv kev sib cuag nrog cov tshuaj aqueous, nws yuav adsorb dej molecules rau ntawm nws qhov chaw, tshem tawm cov dej ntawm cov khoom zoo.

Anhydrous sodium sulfate feem ntau yog siv los tshem tawm cov dej los ntawm cov kuab tshuaj organic (xws li ethanol) thiab cov tshuaj inorganic (xws li acids thiab bases). Nyob rau hauv cov ntaub ntawv no, ib tug me me ntawm anhydrous sodium sulfate yog ntxiv rau cov khoom, thiab cov sib tov yuav nyob twj ywm zoo li qub rau ib lub sij hawm. Thaum lub sij hawm no, anhydrous sodium sulfate adsorbs dej molecules los ntawm cov khoom, tawm hauv qhuav thiab anhydrous khoom. Lub chaw soj nstuam kuj tseem siv anhydrous sodium sulfate kom qhuav gases xws li nitrogen thiab argon. Nyob rau hauv cov ntaub ntawv no, anhydrous sodium sulfate yog nkag mus rau hauv lub raj xa dej los ntawm cov pa roj. Thaum cov roj dhau los ntawm cov kav dej, cov dej vapor uas muaj nyob rau hauv cov pa yog adsorbed los ntawm anhydrous sodium sulfate, tsim cov roj qhuav uas tuaj yeem siv rau kev sim.

Nyob rau hauv luv luv, anhydrous sodium sulfate yog ib qho tseem ceeb dehydrating tus neeg sawv cev, thiab nws lub peev xwm los adsorb dej molecules rau saum npoo yog raws li nws muaj peev xwm los khi nrog hydrogen, tso cai rau nws tsim bonds nrog dej molecules thiab kho lawv nyob rau saum npoo. Siv nyob rau hauv ntau yam tshuaj thiab cov txheej txheem kev lag luam kom tshem tawm cov dej noo los ntawm cov kua thiab roj. Anhydrous sodium sulfate plays lub luag haujlwm tseem ceeb hauv ntau lub chaw soj nstuam thiab cov ntawv thov kev lag luam, txawm tias siv rau ziab cov kuab tshuaj, cov kua qaub, cov hauv paus, lossis cov pa roj.
