LEO says GER

What happens when a substance is reduced or oxidized can be confusing, but there s an easy way to remember it. Just think of a lion, and remember that LEO says GER. This stands for Loss of Eiectrons is Oxidation and Gain of Electrons is Reduction. And no, I didn t come up with that. I m not that clever. 

Oxidation-reduction reactions can be thought of as a combination of two processes oxidation, in which electrons are lost, and reduction, in which electrons are gained. The two processes cannot occur independently of each other. A mnemonic device used by chemists to help keep things straight is LEO says GER, which stands for Loss of Electrons, Oxidation. Gain of Electrons, Reduction. 

C is correct. Ag2+ gains an electron to become Ag+, so it is reduced (LEO says GER). Reduction takes place at the cathode (ANOX/REDCAT). 

If you have trouble remembering the definitions of the terms oxidation and reduction, just remember the little mnemonic device LEO says GER which stands for Losing Electrons is Oxidation, and Gaining Electrons is Reduction... 

A heipfui mnemonic device is Oil RiG (Oxidation Invoives Loss Reduction Invoives Gain). Another common mnemonic is LEO says GER. (Loss of Eiectrons, Oxidation Gain of Eiectrons, Reduction). 

Try using a mnemonic to remember the definitions for oxidation and reduction. For example, in "LEO the lion says GER," LEO stands for "Loss of Electrons is Oxidation." GER stands for "Gain of Electrons is Reduction." The mnemonic "OIL RIG" stands for "Oxidation Is Loss. Reduction Is Gain." Make up your own mnemonic to help you remember these definitions. 

Loss of Electrons is Oxidation = LEO Gain of Electrons is Reduction = GER LEO the lion says GER ... 

In an oxidation-reduction reaction, one compound loses electrons and one compound gains electrons. The compound that loses electrons is oxidized, and the one that gains electrons is reduced. One way to remember the difference between oxidation and reduction is with the phrase LEO the lion says GER Imss of Electrons is Oxidation Gain of Electrons is Reduction. 

Comment A common mnemonic for remembering oxidation and reduction is LEO the lion says GER losing electrons is oxidation gaining electrons is reduction. 

Helpful mnemonics OIL RIG-OxIdatlon Is Loss (of electrons) Reduction Is Gain (of electrons). LEO the Hon says GER-Lose Electrons Oxidation Gain Electrons Reduction.
