From the statements given below, choose the correct statement regarding the galvanic cell.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Reduction occurs at cathode.
Positively charged electrode is called anode.
- Incorrect. The anode in a galvanic cell is the negatively charged electrode.
Negatively charged electrode is called cathode.
- Incorrect. The cathode in a galvanic cell is the positively charged electrode.
Oxidation occurs at cathode.
- Incorrect. Oxidation occurs at the anode (remember the mnemonic: An Ox - Anode is Oxidation).
Reduction occurs at cathode.
- Correct. Reduction occurs at the cathode (remember the mnemonic: Red Cat - Reduction is at the Cathode).
