Which statement best describes oxidation in a redox reaction?
Which statement best describes oxidation in a redox reaction?
- Oxidation is the conversion of iron to an oxide.
- Oxidation is the gain of electrons or a decrease in the oxidation state.
- Oxidation is the loss of electrons or an increase in the oxidation state. (correct)
- Oxidation is the transfer of an atom from one substrate to another.
What is the main difference between electron-transfer and atom transfer redox reactions?
What is the main difference between electron-transfer and atom transfer redox reactions?
- In electron-transfer reactions, electrons are lost by the atom being oxidized, while in atom transfer reactions, electrons are lost by the atom being reduced.
- In electron-transfer reactions, electrons are gained by the atom being oxidized, while in atom transfer reactions, electrons are gained by the atom being reduced.
- There is no difference between electron-transfer and atom transfer redox reactions.
- In electron-transfer reactions, only one electron flows between the atoms, while in atom transfer reactions, multiple electrons are transferred. (correct)

Study Notes
Redox Reactions
- Oxidation in a redox reaction involves the loss of one or more electrons by an atom, molecule, or ion, resulting in an increase in its oxidation state.
Types of Redox Reactions
- The main difference between electron-transfer and atom transfer redox reactions is that electron-transfer reactions involve the transfer of electrons, whereas atom transfer reactions involve the transfer of atoms or groups of atoms.
Role of Electrode Potentials
- Electrode potentials play a crucial role in redox reactions, as they determine the tendency of a species to lose or gain electrons.
Examples of Oxidation Reactions
- The combustion of gasoline in a car engine is an example of an oxidation reaction, where the gasoline (fuel) is oxidized to produce energy.
Alternative Chemical Species in Oxidation Reactions
- Other chemical species that can serve the same function as oxides in oxidation reactions include halogens, such as chlorine and bromine, and nitric acid.
