Electrolysis ntawm Molten Sodium Chloride Thaum melted ntawm qhov kub thiab txias, sodium chloride sib cais rau hauv sodium thiab chloride ions, yog li ntawd, electrolysis tuaj yeem tsim sodium atom thiab chlorine gas. Cov txheej txheem qis: Sodium chloride melts ntawm qhov kub thiab txias ntawm 801 ° C.
Yuav ua li cas thaum molten NaCl yog Electrolysed?
Electrolysis ntawm molten NaCl decomposes qhov sib xyaw no rau hauv nws cov khoom. Electrolysis ntawm aqueous NaCl cov kev daws teeb meem muab kev sib xyaw ntawm hydrogen thiab chlorine gas thiab cov tshuaj aqueous sodium hydroxide.
Yuav ua li cas thaum lub sij hawm electrolysis ntawm sodium chloride niaj hnub?
Metallic sodium thiab chlorine gas yog tsim los ntawm electrolysis ntawm molten sodium chloride; electrolysis ntawm aqueous tov ntawm sodium chloride yields sodium hydroxide thiab chlorine gas. Hydrogen thiab oxygen yog tsim los ntawm electrolysis ntawm dej.
Hom twg tau txo qis ntawm cathode thaum lub sij hawm electrolysis ntawm molten NaCl?
Ntawm lub cathode (C), dej txo kom hydroxide thiab hydrogen gas. Cov txheej txheem net yog electrolysis ntawm aqueous tov ntawm NaCl rau hauv industrially pab tau cov khoom siv sodium hydroxide (NaOH) thiab chlorine gas.
Cov khoom lag luam dab tsi yog tsim ntawm lub anode thaum molten sodium chloride NaCl yog electrolyzed siv Downs cell?
Chlorine gas tseem tsim tawm ntawm lub anode, ib yam li hauv electrolysis ntawm molten NaCl. Txij li thaum hydroxide ions kuj yog ib yam khoom ntawm cov tshuaj tiv thaiv, cov tshuaj tseem ceeb sodium hydroxide (NaOH) yog tau los ntawm evaporation ntawm cov aqueous tov nyob rau hauv lub kawg ntawm hydrolysis.
