Define the following concepts in relation to electron emission – electron absorption.
- Reduction
- Oxidation
- reducing agent
- oxidizing agent
Solution: - Reduction: The substance itself absorbs electrons
- Oxidation: The substance itself releases electrons
- Reducing agent: The substance itself presses electrons onto another (!!) substance, thus having a reducing effect on the other substance. The substance self losing thus electrons, gives thus electrons from, is thus oxidated.
In short: works reducing and is oxidized. - Oxidizing agent: the substance self takes of a other (!!) substance electrons on, it works thus oxidating on the other substance. The substance itself therefore absorbs electrons, is therefore reduced to .
In short: works oxidizing and is reduced.
