I keep getting “Anode and cathode” questions wrong in Electrochemistry. What's the trap?
assuming the anode is always the positive terminal.
The usual trap: assuming the anode is always the positive terminal. How to avoid it: 'An-Ox, Red-Cat' — Anode Oxidation, Reduction Cathode, in every cell. Go back to the definition — oxidation always happens at the anode and reduction always at the cathode.
Key point
Anode and cathode
Common mistake
assuming the anode is always the positive terminal.
Memory tip
