PANIC = Positive Anode, Negative Is Cathode

Use this to remember which electrode is which: the Positive electrode is the Anode, the Negative Is the Cathode.

CATions go to the CAThode — both start with "CAT". ANions go to the ANode — both start with "AN".

OIL RIG — Oxidation Is Loss (of electrons), Reduction Is Gain (of electrons). At the anode = oxidation (loss). At the cathode = reduction (gain).

For the anode burning away: "The ANODE gets ATE — it reacts with oxygen and burns away as CO₂!"

Quick Recall Flashcards

What does OIL RIG stand for?
Oxidation Is Loss (of electrons), Reduction Is Gain (of electrons). At the Anode = Oxidation (loss). At the Cathode = Reduction (gain).
Why do the carbon anodes need replacing regularly?
At 950°C, the oxygen produced at the anode reacts with the hot carbon: C + O₂ → CO₂. The carbon is gradually burned away, so the anodes must be replaced periodically.
