5 Questions
Which statement best describes oxidation in a redox reaction?
Oxidation is the loss of electrons or an increase in the oxidation state.
What is the main 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.
What is the role of electrode potentials in redox reactions?
Electrode potentials determine the direction of redox reactions.
Which of the following is an example of oxidation reaction?
The rusting of iron
What other chemical species can serve the same function as oxides in oxidation reactions?
Carbon
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.
