Why is corrosion considered oxidation?

Answer 1

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.

Answer 2

Rust is an oxidation reaction because the Iron ion (Fe+2) is combining with an Oxygen ion (O-2) in a chemical bond. Some periodic tables have oxidation numbers (even more than one for some elements) in the upper right hand corner of each element's box.

In addition to rust, many ions form common compounds that we use everyday (NaCl is a positive sodium ion combined with a negative chlorine ion).

Simply put, to form ionic bonds, usually two elements will stabilize each other by one element lending a certain number of electrons to the other.

Answer 3

Electrochemical Cells Corrosion is electrochemical in nature because the corrosive chemical reactions involve transfer of charge.

Iron goes into solution as Fe++ ions. As these ions go into solution, the metal becomes negatively charged (by the electrons left behind) with respect to the electrolyte.

Answer 4

Corrosion is the gradual destruction of material, usually metals, by chemical reaction with its environment. In the most common use of the word, this means electro-chemical oxidation of metals in reaction with an oxidant such as oxygen.

Answer 5

Corrosion is considered oxidation because it involves the loss of electrons by a metal atom, which is a key characteristic of oxidation reactions. When metals react with oxygen in the presence of moisture, they undergo a redox reaction where the metal atoms lose electrons to form metal ions, which is an oxidation process.

Answer 6

When a metal such as zinc or copper is exposed to the air (oxygen) it starts to corrode.

Answer 7

corrosion is the destruction of metal caused by its reactivity

Answer 8

It is not the same oxidation is addition of oxygen whilist corrossion is cosing rust
