Electrolysis dej yog txheej txheem los ntawm uas dej decomposed rau hauv oxygen thiab hydrogen gas, thaum hluav taws xob dhau los ntawm nws. Cov dej molecule decomposed nyob rau hauv H + thiab OH- ions, thaum hluav taws xob tam sim no dhau los ntawm nws.
Yuav ua li cas ntawm anode thaum lub sij hawm electrolysis ntawm dej?
Lub electrolysis ntawm dej tsim hydrogen thiab oxygen gases. … Ntawm lub anode, dej yog oxidized rau cov pa roj carbon monoxide thiab hydrogen ions. Ntawm cathode, dej raug txo kom hydrogen gas thiab hydroxide ions.
Yuav ua li cas thaum lub sij hawm electrolysis ntawm dej?
Electrolysis yog txheej txheem ntawm kev siv hluav taws xob los faib dej rau hauv hydrogen thiab oxygen.
Yuav ua li cas rau anode thiab cathode thaum electrolysis?
Electrolysis ntawm acidified dej
H + ions yog nyiam mus rau cathode, nce electrons thiab tsim hydrogen gas . OH - ions yog nyiam rau lub anode, plam electrons thiab tsim oxygen gas.
Cov pa roj twg tau tso tawm ntawm cathode thiab anode thaum electrolysis ntawm dej?
b) Hauv electrolysis ntawm dej, cov roj uas tau sau ntawm cathode yog hydrogen thiab cov roj sau ntawm anode yog oxygen. Cov roj uas tau sau ua ob npaug yog hydrogen. Qhov no yog vim dej muaj ob lub molecules piv rau ib molecule ntawm oxygen.
