Question

write down the electrochemical reaction in the formation of rust on surfact of the iran.​

Answer 1

Answer:

The formation of rust requires iron, water and oxygen. Although it's a complex process, the chemical equation is simply 4Fe + 3O2 + 6H2O → 4Fe(OH)3.

Answer 2

Answer:

Oxidation occurs at the anodes of each electrochemical cell. ... Therefore, at each anode neutral iron atoms are oxidised to ferrous ions. At anode : Thus, the metal atoms in the lattice pass into the solution as ions, leaving electrons on the metal itself.
