MCQ
Which of the following statement is true for an electrochemical cell
  • A
    ${H_2}$is cathode and $Cu$is anode
  • ✓
    ${H_2}$ is anode and $Cu$ is cathode
  • C
    Reduction occurs at ${H_2}$electrode
  • D
    Oxidation occurs at $Cu$ electrode
✓

Answer

Correct option: B.
${H_2}$ is anode and $Cu$ is cathode
b
(b)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.
