Answer 2

Cementation is the saturation of the surface layer of the metal and the ion of the precepitating metal.

• Cementation is a process of extracting metals from a solution by the electrochemical reaction between cementing metal and the precepitating metal.

• Cementation of copper is a common example. The copper ions in the solution precipitate in the presence of solid iron. The iron oxidizes and the copper ions are reduced by the transfer of electrons.

• The reaction is : Cu2+(aq) + Fe(s) → Cu(s) + Fe2+(aq)
