From the statements given below, choose the correct statement regarding the galvanic cell.

Reduction occurs at cathode.

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).
