Iron rusting.

Explanation:

Iron will oxidize in the presence of oxygen and moisture to give iron(III) oxide.

#4Fe^(2+)(aq) + O_2(g) + 4H_2O(l)-> 2Fe_2O_3(s)+ 8H^+(aq)#

The oxidation state of #Fe# is #0# and the oxidation state of iron in #Fe_2O_3# is #+3#.

Oxidation: Increase in the oxidation state.
