Redox Reactions in Terms of Electron Transfer Reactions
Defining oxidation as loss of electrons and reduction as gain of electrons, and identifying redox reactions.
What is Redox Reactions in Terms of Electron Transfer Reactions?
A chemical process involving the loss of electrons by a species, resulting in an increase in its oxidation state.
Key points
- Define oxidation and reduction in terms of electron transfer.
- Identify the oxidizing and reducing agents in a given redox reaction.
- Recognize that redox reactions involve simultaneous oxidation and reduction.
Common exam trap
Confusing oxidizing and reducing agents.
Definitions
- Term
Oxidation
- Meaning
A chemical process involving the loss of electrons by a species, resulting in an increase in its oxidation state.
- Term
Reduction
- Meaning
A chemical process involving the gain of electrons by a species, resulting in a decrease in its oxidation state.
- Term
Redox Reaction
- Meaning
A chemical reaction in which both oxidation and reduction occur simultaneously, involving the transfer of electrons between reactants.
- Term
Oxidizing Agent
- Meaning
A substance that causes oxidation in another substance by accepting electrons from it; it itself gets reduced.
- Term
Reducing Agent
- Meaning
A substance that causes reduction in another substance by donating electrons to it; it itself gets oxidized.
