alleryIn an electrochemical (galvanic) cell, oxidation occurs at the:
ACathode
BAnode
CSalt bridge
DExternal wire
Answer & Solution
Correct answer: B. Anode
1. Mnemonic: 'an OX is a RED CAT' — Oxidation at Anode; Reduction at Cathode.
2. In a galvanic cell, the anode is the NEGATIVE terminal (where electrons leave the cell into the wire).
3. In an electrolytic cell, the SIGN flips but the rule 'anode = oxidation' is the same.
