Rusting of iron becomes quicker in saline medium. Explain.
Asked by Topperlearning User | 22nd Jun, 2016, 03:06: PM
Saline medium has extra salts such as sodium chloride dissolved in water. It has a greater concentration of electrolyte than ordinary medium. The ions present will favor the formation of more electrochemical cells and favor the transfer of hydrogen ions and will thus promote rusting or corrosion.
