Qhov sib txawv tseem ceeb ntawm molten thiab aqueous electrolysis yog tias molten electrolysis tsim cov ntsiab lus ntawm cov tshuaj ntsuam xyuas, whereas aqueous electrolysis tsim cov kua ntsev aqueous thiab cov roj sib tov ua cov khoom kawg.
Molten thiab aqueous electrolysis yog ob hom electrolysis txoj hauv kev analytical chemistry uas txawv ntawm ib leeg raws li cov khoom ntawm qhov nruab nrab electrolytic. Lo lus "molten" yog hais txog cov kua hauv lub xeev ntawm cov tshuaj ntsuam xyuas thaum tsis muaj dej thaum lo lus "aqueous" yog hais txog cov kua hauv lub xub ntiag ntawm dej.
Molten Electrolysis yog dab tsi?
Molten electrolysis yog ib qho txheej txheem hauv analytical chemistry uas siv hluav taws xob tam sim no los cais cov tshuaj hauv cov tshuaj analytes hauv nws lub xeev molten. Feem ntau, ionic compounds yog siv nyob rau hauv hom electrolysis hom. Cov txheej txheem no muab cov ntaub ntawv qhia txog yuav ua li cas peb tuaj yeem rho tawm cov hlau xws li txhuas thiab sodium los ntawm lawv cov molten ionic compounds siv hluav taws xob tam sim no.

Piv txwv li, txhuas yog cov hlau ntau tshaj plaws nyob rau hauv lub ntiaj teb saum npoo, tab sis nws tsis tshwm sim hauv lub xeev ntshiab hauv qhov xwm txheej. Hloov chaw, nws tshwm sim li ionic compounds hauv cov zaub mov. Yog li ntawd, peb yuav tsum cais txhuas los ntawm nws cov tebchaw ntawm electrolysis. Ntawm no, peb siv molten ionic compound. Ib qho ionic compound cov ntaub ntawv vim yog kev tsim cov ionic zog uas muaj nyob nruab nrab ntawm cations thiab anions. Nyob rau hauv lub solid-state ntawm ib tug ionic compound, cov anions thiab cations raug kaw nyob rau hauv ib tug nruj qauv yog li ntawd lawv tsis tuaj yeem ua hluav taws xob. Yog li ntawd, peb tsis tuaj yeem siv cov khoom sib txuas rau electrolysis. Tab sis nyob rau hauv nws lub xeev molten, lub ionic compound cais mus rau hauv anions thiab cations, cia lub xeev molten ntawm lub analyte ua hluav taws xob. Peb tuaj yeem tau txais lub xeev molten los ntawm melting cov khoom. Yog li ntawd, peb tuaj yeem hu lub xeev molten ntawm cov tshuaj ntsuam xyuas ua ib qho electrolyte.
Thaum cov txheej txheem ntawm molten electrolysis, cov cations txav mus rau qhov tsis zoo electrode thaum anions txav mus rau qhov zoo electrode. Ntawm qhov tsis zoo electrode (cathode), cations nce electrons thiab ua atoms. Ntawm qhov zoo electrode lossis anode, ions poob electrons los ua atoms.
Aqueous Electrolysis yog dab tsi?
Aqueous electrolysis yog ib qho txheej txheem hauv analytical chemistry uas siv hluav taws xob tam sim no los cais cov tshuaj hauv cov tshuaj analytes hauv nws lub xeev aqueous. Hom electrolysis no tseem ceeb heev kom tau txais cov khoom tshwj xeeb lossis cov pa roj. Piv txwv li, yog tias peb hla cov hluav taws xob los ntawm dej, nws tsim cov roj hydrogen thiab cov pa oxygen.

Nyob rau hauv cov txheej txheem ntawm aqueous electrolysis, ib qho hluav taws xob tam sim no dhau los ntawm ionized electrolyte; Ntawm no cov cations txav mus rau lub anode thiab anions txav mus rau cathode. Hom kab ke no hu ua electrolytic cell. Muaj ntau ntau daim ntawv thov ntawm aqueous electrolysis, suav nrog electroplating, refining bauxite rau hauv txhuas, tsim cov tshuaj chlorine thiab caustic soda los ntawm lub rooj ntsev, thiab lwm yam.
Qhov txawv ntawm Molten thiab Aqueous Electrolysis yog dab tsi?
Molten thiab aqueous electrolysis yog cov txheej txheem analytical hauv chemistry uas muaj txiaj ntsig zoo hauv kev sib cais cov tshuaj hauv cov tshuaj ntsuam xyuas. Qhov sib txawv tseem ceeb ntawm molten thiab aqueous electrolysis yog tias molten electrolysis tsim cov ntsiab lus ntawm cov tshuaj ntsuam xyuas, whereas aqueous electrolysis tsim cov kua ntsev aqueous thiab cov roj sib tov ua cov khoom kawg.
Hauv qab infographic qhia ntau qhov kev sib piv ntsig txog qhov sib txawv ntawm molten thiab aqueous electrolysis.
Summary – Molten vs Aqueous Electrolysis
Electrolysis yog ib qho txheej txheem hauv kev tshuaj ntsuam chemistry uas suav nrog kev siv hluav taws xob cais cov ntsiab lus hauv cov khoom. Molten thiab aqueous electrolysis yog ob hom electrolysis. Qhov sib txawv tseem ceeb ntawm molten thiab aqueous electrolysis yog tias molten electrolysis tsim cov ntsiab lus ntawm cov tshuaj ntsuam xyuas, thaum aqueous electrolysis tsim cov kua ntsev aqueous thiab cov roj sib tov ua cov khoom kawg.
