Question

What is reducation and its example ​

Answer 1

Reduction involves a half-reaction in which a chemical species decreases its oxidation number, usually by gaining electrons.

Examples of Reduction:

The H+ ions, with an oxidation number of +1, are reduced to H2, with an oxidation number of 0, in the reaction:

Zn(s) + 2H+(aq) → Zn2+(aq) + H2(g)

Another simple example is the reaction between copper oxide and magnesium to yield copper and magnesium oxide:

CuO + Mg → Cu + MgO
