Redox Reactions And Electrochemistry Ques 51
Question: Which of the following statement is true for an electrochemical cell [Pb.CET 2002]
Options:
A) $ H_2 $ is cathode and $ Cu $ is anode
B) $ H_2 $ is anode and Cu is cathode
C) Reduction occurs at $ H_2 $ electrode
D) Oxidation occurs at Cu electrode
Show Answer
Answer:
Correct Answer: B
Solution:
Elements with lower reduction potential act as anode. His placed above Cu in electrochemical series so it has lesser reduction potential and thus act as anode and Cu act as cathode.
