Rusting of Iron - Explanation, Chemical Reaction ...

2021-9-3 · The direct reaction between the iron cations and the hydroxide ions also produces iron hydroxides. O 2 + H 2 O + 4e – → 4OH – Fe 2+ + 2OH – → Fe(OH) 2. Fe 3+ + 3OH – → Fe(OH) 3. The iron hydroxides that result are now dehydrated, yielding the iron oxides that makeup rust. Many chemical processes are involved in this process, some ...

What are the chemical reactions involved in corrosion?

2020-5-12 · Corrosion is a natural process that converts a refined metal into a more chemically-stable form such as oxide, hydroxide, or sulfide. In the most common use of the word, this means electrochemical oxidation of metal in reaction with an oxidant such as oxygen or sulfates. Herein, what type of chemical reaction is involved in corrosion of iron?
