Redox Reactions And Electrochemistry Ques 160
Question: In the electrochemical cell $ H_2(g),1,atm,|{H^{+}}(1M)||C{u^{2+}}(1M),|Cu(s) $ Which one of the following statements is true [EAMCET 1997]
Options:
A) $ H_2 $ is cathode; $ Cu $ is anode
B) Oxidation occurs at $ Cu $ electrode
C) Reduction occurs at $ H_2 $ electrode
D) $ H_2 $ is anode; $ Cu $ is cathode
Show Answer
