Rusting of iron becomes quicker in salin...

Rusting of iron becomes quicker in saline medium. Explain.

Text Solution

Verified by Experts

Saline medium has extra salts such as sodium chloride dissolved in water. This means that it has a greater concentration of electrolyte than ordinary medium. The ions present will favour the formation of more electrochemical cells and will thus promote rusting or corrosion.
