Principles of Electrolysis
Electrolysis uses electrical energy to drive a non-spontaneous chemical reaction. A direct current (DC) passes through an electrolyte (a liquid containing mobile ions), causing chemical decomposition at the electrodes.
Anode (+): Oxidation (Loss of $e^-$)
Cathode (-): Reduction (Gain of $e^-$)
Cathode (-): Reduction (Gain of $e^-$)
Mnemonic (PANIC): Positive is Anode, Negative Is Cathode.
Anions (negative ions) migrate to the Anode. Cations (positive ions) migrate to the Cathode.
Anions (negative ions) migrate to the Anode. Cations (positive ions) migrate to the Cathode.
