alleryIn the Daniell cell, the cathode reaction is:
AZn → Zn²⁺ + 2e⁻
BH₂O → H₂ + O₂
CCu → Cu²⁺ + 2e⁻
DCu²⁺ + 2e⁻ → Cu
Answer & Solution
Correct answer: D. Cu²⁺ + 2e⁻ → Cu
Cathode = reduction.
In Daniell cell, copper electrode is cathode where Cu²⁺ + 2e⁻ → Cu.
Zinc is anode where Zn → Zn²⁺ + 2e⁻ (oxidation).
