Question

define corrosion write the chemical name for the layer formed on Iron copper and silver metal as a result of corrosion

Answer 1

Corrosion is a natural process, which converts a refined metal to a more chemically-stable form, such as its oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually metals) by chemical and/or electrochemical reaction with their environment.

IRON OXIDE : (Fe2O3) - Iron oxide

EQUATION : 4Fe + 3O2 →  2Fe2O

EQUATION :  2Ag + O2 →  Ag2O
