Oxidation and Reduction Reactions
- Oxidation involves the loss of electrons, gain of oxygen, or loss of hydrogen.
- Reduction involves the gain of electrons, loss of oxygen, or gain of hydrogen.
- The mnemonic "LEO the lion says GER" can be used to remember:
- LEO: Loss of Electrons = Oxidation
- GER: Gain of Electrons = Reduction
EXPLANATION:
- If a substance loses hydrogen during a reaction, it is reduced.
This is incorrect, as the loss of hydrogen signifies oxidation, not reduction. - If a substance loses oxygen during a reaction, it is reduced.
This is correct, as reduction involves the loss of oxygen. - If a substance gains hydrogen during a reaction, it is reduced.
This is correct, as reduction involves the gain of hydrogen. - If a substance gains oxygen during a reaction, it is oxidized.
This is correct, as oxidation involves the gain of oxygen.
The incorrect statement is If a substance loses hydrogen during a reaction, it is reduced.
