Iron rusting.

Explanation:

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

$4 F e^{2 +} (a q) + O_{2} (g) + 4 H_{2} O (l) \to 2 F e_{2} O_{3} (s) + 8 H^{+} (a q)$ $4Fe^(2+)(aq) + O_2(g) + 4H_2O(l)-> 2Fe_2O_3(s)+ 8H^+(aq)$

The oxidation state of $F e$ $Fe$ is $0$ $0$ and the oxidation state of iron in $F e_{2} O_{3}$ $Fe_2O_3$ is $+ 3$ $+3$ .

Oxidation: Increase in the oxidation state.
