Memory Aids
The key terms involved in redox are often confusing to students. For example, an element that is oxidized loses electrons; however, that element is referred to as the reducing agent. Likewise, an element that is reduced gains electrons and is referred to as the oxidizing agent. Acronyms or mnemonics are commonly used to help remember what is happening:
- "OIL RIG"—Oxidation Is Loss of electrons, Reduction Is Gain of electrons.
- "LEO the lion says GER" — Loss of Electrons is Oxidation, Gain of Electrons is Reduction.
- "LEORA says GEROA" — Loss of Electrons is Oxidation (Reducing Agent) and Gain of Electrons is Reduced (Oxidizing Agent).

Famous quotes containing the words memory and/or aids:
“There are no stars to-night
But those of memory.
Yet how much room for memory there is
In the loose girdle of soft rain.”
—Hart Crane (1899–1932)
“This whole business of Trade gives me to pause and think, as it constitutes false relations between men; inasmuch as I am prone to count myself relieved of any responsibility to behave well and nobly to that person who I pay with money, whereas if I had not that commodity, I should be put on my good behavior in all companies, and man would be a benefactor to man, as being himself his only certificate that he had a right to those aids and services which each asked of the other.”
—Ralph Waldo Emerson (1803–1882)
