Question

1. The chemical reaction involved in corrosion of iron metal is that of :​

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.

Rust (Fe2O3•xH2O) is formed by the subsequent oxidation of Fe2+ by atmospheric oxygen. In the corrosion process, iron metal acts as the anode in a galvanic cell and is oxidized to Fe2+; oxygen is reduced to water at the cathode.

Answer 2

Explanation:

chemical reaction for coorosion is oxidation reaction

fe+O2 - fe2O3
