Question

Iron pipes, lying in acidic soil, are often attached to the blocks of magnesium for their protection from rusting, because magnesium (A) is lighter than iron (B) is readily converted into positive ion (C) forms a corrosion-resistant alloy with iron (D) prevents air from reaching the surface of iron

Tardigrade Admin · Accepted Answer

Magnesium is readily converted into positive ions when they come in contact of acidic soil. They form laycr of oxide over acidic soil and help in prevention of rusting of iron pipes.
