Iron pipes lying under acidic soil are often attached to blocks of mag – InterviewSolution

1.	Iron pipes lying under acidic soil are often attached to blocks of magnesium offers protection to iron against corrosion because it
Answer» Prevents AIR from reaching the surface of IRON Is more readily converted into POSITIVE ions Is HIGHER electropositive than iron Forms a corrosion-resistance alloy with iron SOLUTION :Due to electropositive and reactive in nature, magnesium is readily converted into positive ions on contact with iron pipes and hence, iron pipes remains as it is.
