LEO GER

Oxidation is the loss of electrons, and reduction is the gain of electrons. Remember LEO GER ... 

Oxidation and reduction are complementary processes oxidation cannot occur unless reduction also occurs. It is important to recognize and distinguish between oxidation and reduction. A memory aid might help you remember the distinction. The phrase Loss of Electrons is Oxidation, and Gain of Electrons is Reduction is shortened to LEO GER. 

Heipfui mnemonics Oil RiG-Oxidation Is Loss Reduction Is Gain. LEO GER—Lose Electrons Oxidation Gain Electrons 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. 

Two commonly used redox / V I reaction memorization aids are 1) LEO the lion goes GER (Lose Electrons Oxidation, Gain Electrons Reduction) and OIL RIG (Oxidation Involves Loss of electrons, Reduction Involves Gain of electrons). 

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. 

Fluoranthene (Called 1,2-benzo-acenaphthy-leo or 1,8-o-phenylen-naphthylen in Ger), CjeHjQ(Thought to be Cj Hjoin early literature), mw 202.24, colorless odls, sp gr 1.158 at 20°, 0 1.739 at 20°, bp 393, 217°(30rain Hg), mp 109.5-110.5° sol In benz, chU, eth, HAc hot ale. A tetracyclic fused ring aromatic hydrocarbon, this material is found in some coal tars. It forms definite complexes with many poly nitrated aromatics (Refs 1 to 6) Refs 1) Beil 5, 685, (340, 344), [609] ... 

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... 

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. 

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). 

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

To help yourself remember which is oxidation and which is reduction in terms of electrons, memorize the phrase LEO goes GER (Lose Electrons Oxidation Gain Electrons deduction). 

Before we discuss the reduction potentials of the alkali metals, we should recall some definitions related to oxidation—reduction, or redox, reactions. (This is but a sparse review. You may need to consult your introductory textbook or lecture notes for further clarification.) Recall that when a substance is reduced, its oxidation state (or the oxidation state of some constituent element) is decreased. When a substance is oxidized, the oxidation state increases. Reduction is associated with a gain of electrons, whereas oxidation corresponds to a loss. (Some students keep these definitions straight by using the mnemonic, or memory device, LEO goes GER, which stands for Loses Llectrons Oxidized, Gains Electrons Reduced.)...
