At which electrode does reduction occur in an electrolytic cell?

Answer and explanation

Correct answer: D. The cathode

  1. Step 1: Reduction always occurs at the cathode. Step 2. Electrons arrive there. Answer: the cathode. Why not the others: Oxidation occurs at the anode; the connecting wire conducts electronic current; and the salt bridge maintains electrical neutrality by ion migration without redox transfer.
