Highly conducting solution favour rapid ...

Highly conducting solution favour rapid corrosion. Explain.

Text Solution

Verified by Experts

Corrosion generally involves oxidation of metal. If metal is in contact with high ionic concentrations, it favours oxidation. Atmospheric corrosion resulting from exposure of a metal to air generally contains water vapour, `H_2S, CO_2, SO_2` etc. These materials are responsible for electrochemical corrosion.
