In a galvanic (voltaic) cell, at which electrode does oxidation occur?
Answer and explanation
Correct answer: C. Anode
- Step 1: By electrochemical convention (mnemonic AN OX, RED CAT):
- Step 2: Oxidation (loss of electrons) always occurs at the anode, while reduction (gain of electrons) occurs at the cathode.
Answer
Anode.
Why not the others: 'Cathode' is the site of reduction where electrons are consumed; 'Salt bridge' maintains electrical neutrality by ion migration; 'Voltmeter' measures cell potential.
