A iron rod on the surface of the beach and other iron rod into the sea water which metal corrodes easily?Ans) An iron rod on the surface of teh seawater because in sea it contains more salts like Na,k,Ca......these salts directly react with the metal surfaces automatically it corrodes very fastly but where as in beach water it doesn''t contain higher amount of these ions so that''s why it f corrodes very late as compared to the sea water
