Contents
Key Stage 4 Foundation
Meaning
Reduction is when a metal oxide loses one or more Oxygen atoms.
About Reduction
- Reduction takes place in displacement reactions involving metal oxides.
In the following redox reaction:
- Aluminium + Iron Oxide → Aluminium Oxide + Iron
- <chem>2Al+Fe2O3->Al2O3+2Fe</chem>
The Iron is reduced because it loses the Oxygen atoms.
Key Stage 4 Higher
Meaning
Reduction is when a positive ion in an ionic compound gains electrons.
About Reduction
- Reduction takes place in displacement reactions.
In the following redox reaction:
- Magnesium + Copper (II) Chloride → Magnesium Chloride + Copper
- Reduction of Copper: <chem>Cu^2+ + 2e^- -> Cu</chem>
The Copper is reduced because it gains electrons.
