OXIDATION-REDUCTION
Oxidation and reduction in terms of oxygen transfer
Definitions
Definitions
- Oxidation is gain of oxygen.
- Reduction is loss of oxygen.
Oxidising and reducing agents
An oxidising agent is substance which oxidises something else. In the above example, the iron(III) oxide is the oxidising agent.
A reducing agent reduces something else. In the equation, the carbon monoxide is the reducing agent.

Definitions
- Oxidising agents give oxygen to another substance.
- Reducing agents remove oxygen from another substance.
Oxidation and reduction in terms of hydrogen transfer
These are old definitions which aren't used very much nowadays. The most likely place you will come across them is in organic chemistry.
