Question : Iron rusts quickly in
Option 1: Rain water
Option 2: Sea water
Option 3: Distilled water
Option 4: River water
Correct Answer: Sea water
Solution : The correct option is sea water.
When exposed to seawater, iron rusts faster than when exposed to freshwater or dry circumstances. Seawater includes dissolved salts and minerals that can speed up the corrosion of iron and other metals, resulting in the production of iron oxide, often known as rust. The increased electrical conductivity of seawater accelerates the electrochemical processes that contribute to rust development. As a result, iron items exposed to seawater rust faster than those exposed to freshwater or dry environments.
