Corrosion of

Options

A. an oxidation process
B. a redox process
C. a redox process
D. neither an oxidation nor a redox process

Answer

C

Explanation

Corrosion processes are electron trsfers, oxidation-reduction processes that occur when the surface of a metal is in contact with atmosphere.
A potential difference in the composition of the metal, which aries from lattice defects, imprities, or even partial oxidation. This potential difference makes it possible for a corrosion process resembling the operation of a galvanic cell to take place on the metal surface.
The site of oxidation and the site of the reduction can be separeted in space. Electrons flow betwenn these sites through electrical connection of a glavanic cell. Water vapor that condness on the metal surface provides the solution through which the ions flow.
