because when corrosion occours on a metal the chemical reaction is an oxidation. This means that the metal will loose electrons and became a positive ion.

Fe ------> Fe 2+ + 2 e-

The iron is oxydised from metal to metal ion.

What type of reaction is occurring when a metal undergoes corrosion?

Corrosion of a metal is an electrochemical reaction where the metal undergoes oxidation, leading to the formation of metal oxides or other compounds. This process is typically accelerated in the presence of moisture or salts in the environment.


What is metal corrosion?

Metal Corrosion or Metallic Corrosion can be defined as the destructive attack of a metal through interaction with its environment.The most common example is Rust, an iron oxide Fe2O3, that is the consequence of the Corrosion process of Iron.


Why is NO3 to NO a reduction?

In the reaction where NO₃^- is reduced to NO, nitrogen changes from a higher oxidation state (+5 in NO₃^-) to a lower oxidation state (+2 in NO). This reduction process involves gaining electrons and therefore is considered a reduction reaction.


Does iodine rust?

No, iodine does not rust because rusting is a specific type of corrosion that occurs only in metals, particularly iron and steel, when exposed to oxygen and moisture. Iodine is a non-metallic element that does not exhibit rusting behavior.


Why is fire considered an example of oxidation?

Fire is considered an example of oxidation because it involves a chemical reaction where a substance combines with oxygen, releasing heat and light. In the case of fire, the substance undergoing oxidation is typically a fuel, such as wood or gas, which reacts with oxygen from the air to produce heat, light, and new chemical compounds. This process is known as combustion.
