Answer:
Rusting of iron is an example of a redox reaction.
Explanation:
During rusting, iron combines with oxygen in the presence of water. This is an oxidation reaction where oxygen acts as an oxidising agent. Since oxygen also combines with the metal iron, this is a reduction reaction, where the metal iron acts as a reducing agent.
Explanation:
During rusting, iron gets oxidised to form rust (Fe

O), which is reddish brown in color.
The reaction of the rusting of iron involves an increase in the oxidation state of iron, accompanied by a loss of electrons. Rust is mostly made up of two different oxides of iron that vary in the oxidation state of the iron atom. These oxides are:
1) Iron(II) oxide or ferrous oxide. The oxidation state of iron in this compound is +2 and its chemical formula is FeO.
2) Iron(III) oxide or ferric oxide, where the iron atom exhibits an oxidation state of +3. The chemical formula of this compound is Fe
