Question

Why rusting takes place very fast with sea water.Please explain it in about 50 words.

Answer 1

Rusting is merely an oxidation process.It involves removal of electrons.

Sea water contains salts (NaCl) , removal of electrons is faster in Sodium chloride as it is an electrolyte that means it conducts charges ( electrons) fast.But freshwater has no electrolyte that can transfer electrons fast.

Hence, rusting takes place faster in saline water or sea water ....

Answer 2

See, If we talking about fresh water or sea water , water enables oxidation.

Salt water or sea water is a very good conductor having lots of dissociated ions.

Because of this ions , there are a number of electrolysis reaction occurs.

And finally accelerate corrosion.

Hope it's useful for your understanding.

All the best.
