Question

What is ${\mathrm{Fe}}_2{\mathrm{O}}_3.{\mathrm{xH}}_2\mathrm{O}$?

Answer 1

4. Rusting of Iron occurs on the surface of Iron as well as alloys.
5. The formation of rust is called Hydrated Iron(III) oxide.
6. The chemical formula of rust is${\mathrm{Fe}}_2{O}_3.{\mathrm{xH}}_{2}O$.
7. The flaky substance formed can be crumbled to form a powder.
