<p>definition</p>
<p><b>New page</b></p><div>Chemical '''reduction''' is the process of lowering the oxidation state of an ion. The canonical example of reduction is that of reducing ore (in the form of a metallic oxide or sulfide) to metal. Chemically, reduction reactions are always paired with oxidation reactions: when one element is reduced, another is oxidized. The paired reactions are together referred to as a ''redox'' reaction. In the case of reduction of ore to metal, while the oxidation state of the metal is reduced, the oxidation state of the oxygen ions increase.<br />
<br />
An example reduction of iron ore:<br />
<br />
2 FeO<sub>2</sub>O<sub>3</sub>---->2 Fe + 3 O<SUB>2</SUB> <br />
<br />
In this reaction, the oxidation state of the iron (Fe) is ''reduced'' from +3 in the ore, to 0 in the metal, while the oxidation state of the oxygen (O) ''increases'' from -2 to 0.<br />
<br />
Reduction reactions are used for [[LUNOX | production of oxygen]] from lunar [[regolith]].<br />
<br />
