Created page with "==Key Stage 4 Foundation== ===Meaning=== '''Reduction''' is when a metal oxide loses one or more Oxygen atoms. ===About Reduction=== : Reduction t..."

New page

==Key Stage 4 Foundation==
===Meaning===
'''Reduction''' is when a [[Metal Oxide|metal oxide]] loses one or more [[Oxygen]] [[atom]]s.

===About Reduction===
: [[Reduction]] takes place in [[Displacement Reaction|displacement reactions]] involving [[Metal Oxide|metal oxides]].
In the following '''redox reaction''':
: [[Aluminium]] + [[Iron Oxide]] → [[Aluminium Oxide]] + [[Iron]]
: <chem>2Al+Fe2O3->Al2O3+2Fe</chem>
The [[Iron]] is [[Reduction|reduced]] because it loses the [[Oxygen]] [[atom]]s.

==Key Stage 4 Higher==
===Meaning===
'''Reduction''' is when a [[Positive Ion|positive ion]] in an [[Ionic Compound|ionic compound]] gains [[electron]]s.

===About Reduction===
: '''Reduction''' takes place in [[Displacement Reaction|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 [[Reduction|reduced]] because it gains [[electron]]s.
