3 Mnemonic Devices for Redox Reactions (Reduction & Oxidation)

Redox Reactions

Need a mnemonic device to keep your redox reactions straight? Here are some memory aids for oxidation and reduction.

1. Lose Electrons: Oxidation, Gain Electrons: Reduction

Redox Reactions LeoGer: Loss of Electrons is Oxidation; Gain of Electrons is Reduction

2. Reduction at the Cathode, Anode Is for Oxidation

And here’s one more mnemonic device. Sorry, no picture.


Oxidation Is Loss (of e-), Reduction Is Gain.


I also found “LEORA says GEROA” (Loss of Electrons is Oxidation–Reducing Agent, Gain of Electrons is Reduction–Oxidizing Agent), but I think you need a mnemonic device to remember this mnemonic device.
